Whether you are an employer or an employee, you need to think beyond résumés to stay ahead of the game.

From hackathons to automated evaluation tools, semantic analysis to personality tests, social hiring to website scraping, recruiting is being reinvented and how.

A “one-size-fits-all” strategy certainly doesn’t cut it.

Résumés will take you only so far.

Research shows that context-dependent skills and passion for the job will continue to drive hiring more than ever.

Here is a quick overview of the top nine sources when scouting for technical talent.

Even if you are not a programmer yourself, these places should help you build a good talent pipeline.

LinkedIn

How are recruiters using LinkedIn for hiring developers?

Recruiters can post jobs, source talent, and build the company brand easily using LinkedIn Talent Solutions.

LinkedIn has over 400 million people! Follow etiquette before all else for optimal results.

Use your profile and company page

Potential candidates will see your personal brand as a reflection of the employer brand.

A good recruiting profile has a friendly profile picture, an interesting descriptive headline, a summary that showcases your professional story and the company culture, goals, accomplishments, and candidate expectations in the best possible light.

Encourage discussions to build your brand.

Establish yourself as a thought leader by publishing engaging, insightful content, either curated or original.

Create a career page, apart from your company page.

  • Read a bit about the publishing platform, LinkedIn Pulse, here.
  • Read more on how to share content using this news aggregation feed here.

Use the built-in analytics features to capture valuable insights for data-driven recruiting.

  • Read more on how to attract followers here.

Extend your reach via engaging status updates about your company’s activities.

To target relevant candidates, try sponsored updates.

Say, your company is organizing a Swift hackathon, then you can sponsor an update to software professionals and students nearby, expanding your network with new followers.

Use the built-in dashboard to study the impressions, engagement, clicks, shares, likes, and acquisition.

  • Read more on some best practices for sponsored content here.

*Note that you can’t publish sponsored updates without a company page and an advertising account.

Use your network

Beef up your existing network through content that might interest programmers. Once again, use sponsored content or company updates to grab attention.

LinkedIn Elevate gives your employees quality shareable content, thereby influencing future recruits in their networks.

People are more likely to believe employees than recruiter spiel. Studies show that people who use this tool,

  • share four times more than before
  • drive forty percent more followers
  • drive three times more job views

Build a referral chain, and run referral contests or referral programs that reward the participants.

*Data suggests that “it takes 29 days to hire a referred candidate, 39 days to hire a candidate through a job posting, and 55 days to hire a candidate through a career site.”

  • Go here to see how you can use LinkedIn Referrals to get the most out of your employees’ networks.
  • Go here to see different types of referral programs to source the best candidates.

One of the most effective ways to humanize your brand is by adding recommendations or testimonials.

Don’t forget to tag connections.

For example, a recruiter can group Python developers using tags.

Scan the events section for valuable connections in the attendee list. Or, list an event to spread the word.

Use ads

LinkedIn has a minimum daily budget that you have to spend on your ads.

Your ROI is much higher than any other internet advertising mediums.

You can attract the attention of people who are checking out profiles of employees in your organization by using Recruitment Ads beside these employee profiles.

  • Go here for some inspirational ads to boost hiring.

Sponsored ads specifically reach the right audience and have proved to be very useful in getting new followers.

Text ads simply display the information you provide under the column “ads you make like” on the right side.

They are also highly-targeted.

Personalized messages can be delivered to a target hire’s inbox.

Use paid options

LinkedIn offers paid services to find passive candidates with access to a wider pool of talent and features to “build a candidate pipeline.”

The advanced search and filter options on offer with a premium account help you source quickly and nurture relationships with top talent easily.

Free (typically done via status updates, job discussions/groups, or creative presentations) and paid job advertising gets you relevant clicks from your target audience.

  • Read more about job posting prices here.

Use groups and join discussions

Participating in group discussions can be really effective to increase the visibility of your brand among the developers and foster your relationship with them.

Here are a few LinkedIn groups that you as an IT recruiter should join for networking, knowing about the latest trends in tech, engaging with the talent, and posting jobs:

You don’t need to actually join a group such as Austin Digital Jobs to get access to the members.

Facebook, Twitter, Snapchat, Google+, Instagram

Everything is digital now. Recruitment too. When 30% of all Google searches are related to employment, there’s little need for further introduction.

If you look at Dice Social Recruiting in Tech Survey 2016-17, you’ll see that recruiters are going all out with social tools with a remarkable success rate.

Facebook

Every minute, users update 293,000 statuses and upload 136,000 photos on Facebook (FB).

This is definitely a talent bank you can’t ignore as a recruiter.

Recruiting through Facebook is a quick and cost-effective way to source local talent, especially for small businesses or startups.

  • Use creative job postings on your company’s FB page and leverage the customization options for maximum benefit.
  • Create a buzz about your company goals and culture in your target market (say, Java developers) through short videos or photos.
  • Connect with potential programmers (or have a page manager) and ensure you engage with them via discussions and quick responses to queries.
  • Add job tabs on your FB page using your ATS.
  • Join relevant groups such as The Facebook Corporate Recruiters Network and Recruiters Online for hiring tips and networking.
  • Encourage employee referral activity.
  • When your company creates an ad with great visuals, make sure it includes all pertinent job posting details.
  • Go here for WordStream’s infographic on ad targeting options FB offers.
  • Read about FB ad types, costs/pricing, and guidelines here.

Tips

  • Find suitable programmers using the FB Graph Search feature. Organic search can’t help you look beyond employees’ friends.
    • Read how to use the graph search option for recruiting here.
    • Don’t create work and a personal FB account as this is against the Terms of Service. Create a “candidates” list and make employer information and hiring posts available only to that audience. Only you know about the privacy restrictions.
  • GitHub

    GitHub is an online project-hosting service site where developers share their open- source projects.

    You can collect contact information from this hotbed of emerging and established technical talent from around the globe.

    Perhaps no other platform has so many programmers in one place. “It is the largest code host in the world.”

    • Once you have a public account up and running, you can get details such as a candidate’s current employer, location, email address, websites she has chosen to display, number of followers (the number telling how good they are at what they do and how respected), GitHub contributions (notice the keywords, for example, Django, Ruby on Rails), and repositories.
    • Your search could be:language: ruby location: San Jose followers: > 15.
    • After filtering your search results (best matches on top), you can reach out to people of interest. Remember to do a bit of research about their work on the site, public activity, and cross-check on other social media sites if possible.
    • You want Code listed as Sources, not Forked.

    Tips

    • Use tools such as SourceHub to find candidates easily.
    • Note that GitHub wasn’t designed for sourcing, so people may not respond. Find a less direct way to approach them.
    • Pick a talented programmer from your company, find her on GitHub, and identify similar people from the follower list.
  • Stack Overflow

    Stack Overflow is an online community for programmers to learn, share their knowledge, and advance their careers.

    Currently, it’s a community of 6.9 million programmers where sort-out developers post their day-to-day questions seeking help and advice from other developers.

    • Use Google search bar to search for candidates with specific skill-set in a particular location because the Stack Overflow search interface is limited. For example, to find android developers in the “Portland” area, in the Google search bar, you can type: “site:stackoverflow.com/users Android (“location*oregon” ”location*portland” ”location*or”)
    • Add a tag (say, the area of expertise such as Flask) as the keyword to find developers who posted or answered questions from that tag.
    • Use Stack Overflow job listings portal to subscribe to Stack Overflow talent.
    how to hire programmers, hire programmers, hire developers, how to hire developers. hire developers, hiring developers, how to hire developers efficiently, best way to hire developers
    • You can find basic details and summary about programmers, answers they have provided, questions they’ve asked, and a rank/reputation based on how the candidates’ questions and answers are perceived by others.

    Tip

    • Use Stack Overflow badges to search for great candidates.
    • Find passive candidates by going to the Careers section; you’ll get an idea about what sort of opportunities they may be looking for.
    • Construct MySQL queries to search data.stackexchange.com.
    • Use properly constructed simple queries on recruitin.net to search Stack Overflow.
      • Read more about sourcing programmers using GitHub and StackOverflow here.
  • Reddit

    Reddit is an online community where users submit content, such as text posts or direct links, in very specific “subreddits” (areas of interest such as news, gaming, music, books, and technology).

    Users can vote submissions up or down.

    As of early 2017, Reddit had 542 million monthly visitors (234 million unique users) and was the seventh most visited website in the US.

    Various developers and thought leaders ask questions and discussion on technology in the Technology section. This can be an amazing place for you to discover highly skilled programmers.

    • Create a personal or company profile after you’ve understood the somewhat complex interface.
    • Use the search bar to find relevant subreddits using keywords like technical hiring, hire, tech jobs etc.
      • Note that Reddit has its own Boolean search terminology. Although it is more limited than some other sites such as LinkedIn, if you are looking for a Python developer who is actively looking to be hired, you can try this: subreddit:forhire selftext:python. If this gets you too many results, use more filters such as time.
    • Once you find your subreddit, you can share your well-defined job description after you read the Rules.
    • You can also contact a Redditor looking for a job in the technical domain.
    how to hire programmers, hire programmers, hire developers, how to hire developers. hire developers, hiring developers, how to hire developers efficiently, best way to hire developers

    Tips

    • Go here for a recruitment subreddit.
    • Download this plugin to answer queries from Redditors without having to log in to Reddit.
    • Desktop users should install this enhancement suite.
    • Message the moderators if you find your post has gone to spam.
    • Before all else, learn the “Reddiquettes.”
  • Quora

    Quora is a Q&A site which facilitates social interactions and interesting conversations.

    • Just like you would when using any niche community for recruiting, you will need to first establish yourself as a thought leader, for example, by answering questions on hiring. Build your reputation.
    • You can identify domain experts by going through topics of interest. For example, if you are interested in Go, you can find people who consistently provide accurate answers.
    • Initiate conversations with the experts and keep in touch. You may just be the recruiter of choice when they start looking for jobs!
      • Read more on how to use Quora for hiring here.

    Tips

    • If nothing else, listen to what people are saying about your company and hiring process. This will help you design your strategy better.
    • Pick up pointers on better-recruiting processes, developers’ pain points, and general know-how in the tech area.
  • Glassdoor

    “Glassdoor is a bit like TripAdvisor for HR, gathering user-generated, anonymous reviews about companies and company life,” says Jonathan Bright in his post on the Business 2 Community website. The candid content prompts potential hires to check out employer ratings before they sign on the dotted lines. A promising tool for recruiting, Glassdoor exerts a huge social influence on job aspirants.

    • Sign up for an Enhanced Employer Profile and make the most of it. Tap into the potential hires’ needs, paint wonderful pictures of the work culture, growth opportunities, work-life balance, and other company policies (which are true, of course).
    • Go here to know more about Glassdoor for Employers.
    • Take pains with your Employee Value Proposition. How you present it and how you promote your company brand makes or breaks a deal.
    how to hire programmers, hire programmers, hire developers, how to hire developers. hire developers, hiring developers, how to hire developers efficiently, best way to hire developers

    Tips

    • It is hard to fake content on Glassdoor. So, be genuine and transparent and earn trust.
    • Gather “competitive intelligence” from Glassdoor before you create your employer profile.
    • Use metrics to better identify your target audience and tailor your hiring approach.
    • Glassdoor offers paid advertising options.
    • Go here for a Glassdoor recruiting tutorial.
  • Meet-ups and developer events

    Meetup.com is an amazing networking site which unites people with shared professional interests.

    With 30.3 million members and more than 0.25 million groups, it’s one of the largest networks of developers all around the world.

    Meetup allows members to find and join groups unified by a common interest. It’s designed so that organizers can manage events associated with in-person meetings.

    For individuals, it can help them find groups that fit their interests and attend events in their preferred location.

    But you can use meetup to find potential candidates without having to go to any events as many of meetup’s groups and attendee lists are public.

    • Find groups of interest (according to location, skills, etc.) using specific keywords. For example, you can find tech meetups within 25 miles of Melbourne, you can browse by country, state, city and the topic of your interest (in our case, it’s tech).
    • Look at the meetup members’ profile and evaluate them through their introduction, interests, and answers to group questions. (Highlight “members” in the image.)
    • Get a list of other groups they’ve joined. This would help demarcate serious ones from the others. Also, you’ll get to know about their interest areas. (Highlight Members of 11 other meetups.)
    • Once you’ve made your interest list, for reference, check their Twitter, Google+, blogs, or sites (if any) to know more about them. Once you’ve filtered your candidates, you can send them a personalized email through meetup which goes to their personal e-mail address as that’s the same address where their meetup updates are sent to.

    In this era of digitalization, we daily come across innumerable ads, emails, offers, sales pitches and a lot of other things.

    So as a recruiter, how can you differentiate yourself and your company from others?

    Personal relationships not only can enable you and your organization to stand out but can create an image of an outstanding brand for which people would want to work.

    And to develop these relationships, as a recruiter, developer events can provide you with an opportunity to network with the most sort-out technical experts.

    You can make connections and build mutually beneficial relationships with them.

    These events happen around the year globally and your colleagues and you can be part of it.

    Over coffee, lunch, or cocktails, you can make connections and spread awareness about how awesome your company is for the developers.

    Maybe at a breakout session, you may find your next tech star.

    how to hire programmers, hire programmers, hire developers, how to hire developers. hire developers, hiring developers, how to hire developers efficiently, best way to hire developers

    Tips

    • There are various sites which provide you with information about these events. Search on Google will give you these on top:
  • Hackathons

    Companies conduct hackathons to foster innovation and get out-of-the-box ideas to create efficient and highly effective products.

    Irrespective of the format or theme of a hackathon, participants are expected to build something from scratch and typically complete the challenge with a working prototype.

    Hackathons are one of their favorite talent-discovery activities, say recruiters.

    External hackathons are amazing places to network with exceptional talent and industry experts.

    You can skillfully build a talent pipeline of hardworking, smart, and passionate programmers by attending the right events.

    The participants will need to work collaboratively and competitively against time and resource constraints; this gives a recruiter a complete picture of the programmers in their “natural habitat.”

    Companies also conduct internal hackathons to crowdsource ideas and identify untapped exceptional talent in their workforce.

    • Read more about how hackathons can be leveraged by HR here.
    how to hire programmers, hire programmers, hire developers, how to hire developers. hire developers, hiring developers, how to hire developers efficiently, best way to hire developers

    Tips

    • Go here for some pointers on how to successfully recruit at hackathons.
      • Companies such as HackerEarth and Hackfest offer platforms to conduct, manage, or organize hackathons easily.

Conclusion

Recruiters can use these ideas to rope in the best programmers looking for a challenging and rewarding opportunities. Admittedly, finding them can be overwhelming.

No matter which source you turn to, remember to hire a programmer who fits into your work environment in terms of vision and commitment.

To ensure better chances of success, you can give them audition projects or bring them on board as consultants initially.

Take your time.

There’s more to a programmer than knowing how to code.It’s really just about logical thinking and analysis,” says Zack Haehn, Bloomberg’s Software Engineering Head.

So, hire for proven capability.

How I used VibeCode Arena platform to build code using AI and leant how to improve it

I Used AI to Build a "Simple Image Carousel" at VibeCodeArena. It Found 15+ Issues and Taught Me How to Fix Them.

My Learning Journey

I wanted to understand what separates working code from good code. So I used VibeCodeArena.ai to pick a problem statement where different LLMs produce code for the same prompt. Upon landing on the main page of VibeCodeArena, I could see different challenges. Since I was interested in an Image carousal application, I picked the challenge with the prompt "Make a simple image carousel that lets users click 'next' and 'previous' buttons to cycle through images."

Within seconds, I had code from multiple LLMs, including DeepSeek, Mistral, GPT, and Llama. Each code sample also had an objective evaluation score. I was pleasantly surprised to see so many solutions for the same problem. I picked gpt-oss-20b model from OpenAI. For this experiment, I wanted to focus on learning how to code better so either one of the LLMs could have worked. But VibeCodeArena can also be used to evaluate different LLMs to help make a decision about which model to use for what problem statement.

The model had produced a clean HTML, CSS, and JavaScript. The code looked professional. I could see the preview of the code by clicking on the render icon. It worked perfectly in my browser. The carousel was smooth, and the images loaded beautifully.

But was it actually good code?

I had no idea. That's when I decided to look at the evaluation metrics

What I Thought Was "Good Code"

A working image carousel with:

  • Clean, semantic HTML
  • Smooth CSS transitions
  • Keyboard navigation support
  • ARIA labels for accessibility
  • Error handling for failed images

It looked like something a senior developer would write. But I had questions:

Was it secure? Was it optimized? Would it scale? Were there better ways to structure it?

Without objective evaluation, I had no answers. So, I proceeded to look at the detailed evaluation metrics for this code

What VibeCodeArena's Evaluation Showed

The platform's objective evaluation revealed issues I never would have spotted:

Security Vulnerabilities (The Scary Ones)

No Content Security Policy (CSP): My carousel was wide open to XSS attacks. Anyone could inject malicious scripts through the image URLs or manipulate the DOM. VibeCodeArena flagged this immediately and recommended implementing CSP headers.

Missing Input Validation: The platform pointed out that while the code handles image errors, it doesn't validate or sanitize the image sources. A malicious actor could potentially exploit this.

Hardcoded Configuration: Image URLs and settings were hardcoded directly in the code. The platform recommended using environment variables instead - a best practice I completely overlooked.

SQL Injection Vulnerability Patterns: Even though this carousel doesn't use a database, the platform flagged coding patterns that could lead to SQL injection in similar contexts. This kind of forward-thinking analysis helps prevent copy-paste security disasters.

Performance Problems (The Silent Killers)

DOM Structure Depth (15 levels): VibeCodeArena measured my DOM at 15 levels deep. I had no idea. This creates unnecessary rendering overhead that would get worse as the carousel scales.

Expensive DOM Queries: The JavaScript was repeatedly querying the DOM without caching results. Under load, this would create performance bottlenecks I'd never notice in local testing.

Missing Performance Optimizations: The platform provided a checklist of optimizations I didn't even know existed:

  • No DNS-prefetch hints for external image domains
  • Missing width/height attributes causing layout shift
  • No preload directives for critical resources
  • Missing CSS containment properties
  • No will-change property for animated elements

Each of these seems minor, but together they compound into a poor user experience.

Code Quality Issues (The Technical Debt)

High Nesting Depth (4 levels): My JavaScript had logic nested 4 levels deep. VibeCodeArena flagged this as a maintainability concern and suggested flattening the logic.

Overly Specific CSS Selectors (depth: 9): My CSS had selectors 9 levels deep, making it brittle and hard to refactor. I thought I was being thorough; I was actually creating maintenance nightmares.

Code Duplication (7.9%): The platform detected nearly 8% code duplication across files. That's technical debt accumulating from day one.

Moderate Maintainability Index (67.5): While not terrible, the platform showed there's significant room for improvement in code maintainability.

Missing Best Practices (The Professional Touches)

The platform also flagged missing elements that separate hobby projects from professional code:

  • No 'use strict' directive in JavaScript
  • Missing package.json for dependency management
  • No test files
  • Missing README documentation
  • No .gitignore or version control setup
  • Could use functional array methods for cleaner code
  • Missing CSS animations for enhanced UX

The "Aha" Moment

Here's what hit me: I had no framework for evaluating code quality beyond "does it work?"

The carousel functioned. It was accessible. It had error handling. But I couldn't tell you if it was secure, optimized, or maintainable.

VibeCodeArena gave me that framework. It didn't just point out problems, it taught me what production-ready code looks like.

My New Workflow: The Learning Loop

This is when I discovered the real power of the platform. Here's my process now:

Step 1: Generate Code Using VibeCodeArena

I start with a prompt and let the AI generate the initial solution. This gives me a working baseline.

Step 2: Analyze Across Several Metrics

I can get comprehensive analysis across:

  • Security vulnerabilities
  • Performance/Efficiency issues
  • Performance optimization opportunities
  • Code Quality improvements

This is where I learn. Each issue includes explanation of why it matters and how to fix it.

Step 3: Click "Challenge" and Improve

Here's the game-changer: I click the "Challenge" button and start fixing the issues based on the suggestions. This turns passive reading into active learning.

Do I implement CSP headers correctly? Does flattening the nested logic actually improve readability? What happens when I add dns-prefetch hints?

I can even use AI to help improve my code. For this action, I can use from a list of several available models that don't need to be the same one that generated the code. This helps me to explore which models are good at what kind of tasks.

For my experiment, I decided to work on two suggestions provided by VibeCodeArena by preloading critical CSS/JS resources with <link rel="preload"> for faster rendering in index.html and by adding explicit width and height attributes to images to prevent layout shift in index.html. The code editor gave me change summary before I submitted by code for evaluation.

Step 4: Submit for Evaluation

After making improvements, I submit my code for evaluation. Now I see:

  • What actually improved (and by how much)
  • What new issues I might have introduced
  • Where I still have room to grow

Step 5: Hey, I Can Beat AI

My changes helped improve the performance metric of this simple code from 82% to 83% - Yay! But this was just one small change. I now believe that by acting upon multiple suggestions, I can easily improve the quality of the code that I write versus just relying on prompts.

Each improvement can move me up the leaderboard. I'm not just learning in isolation—I'm seeing how my solutions compare to other developers and AI models.

So, this is the loop: Generate → Analyze → Challenge → Improve → Measure → Repeat.

Every iteration makes me better at both evaluating AI code and writing better prompts.

What This Means for Learning to Code with AI

This experience taught me three critical lessons:

1. Working ≠ Good Code

AI models are incredible at generating code that functions. But "it works" tells you nothing about security, performance, or maintainability.

The gap between "functional" and "production-ready" is where real learning happens. VibeCodeArena makes that gap visible and teachable.

2. Improvement Requires Measurement

I used to iterate on code blindly: "This seems better... I think?"

Now I know exactly what improved. When I flatten nested logic, I see the maintainability index go up. When I add CSP headers, I see security scores improve. When I optimize selectors, I see performance gains.

Measurement transforms vague improvement into concrete progress.

3. Competition Accelerates Learning

The leaderboard changed everything for me. I'm not just trying to write "good enough" code—I'm trying to climb past other developers and even beat the AI models.

This competitive element keeps me pushing to learn one more optimization, fix one more issue, implement one more best practice.

How the Platform Helps Me Become A Better Programmer

VibeCodeArena isn't just an evaluation tool—it's a structured learning environment. Here's what makes it effective:

Immediate Feedback: I see issues the moment I submit code, not weeks later in code review.

Contextual Education: Each issue comes with explanation and guidance. I learn why something matters, not just that it's wrong.

Iterative Improvement: The "Challenge" button transforms evaluation into action. I learn by doing, not just reading.

Measurable Progress: I can track my improvement over time—both in code quality scores and leaderboard position.

Comparative Learning: Seeing how my solutions stack up against others shows me what's possible and motivates me to reach higher.

What I've Learned So Far

Through this iterative process, I've gained practical knowledge I never would have developed just reading documentation:

  • How to implement Content Security Policy correctly
  • Why DOM depth matters for rendering performance
  • What CSS containment does and when to use it
  • How to structure code for better maintainability
  • Which performance optimizations actually make a difference

Each "Challenge" cycle teaches me something new. And because I'm measuring the impact, I know what actually works.

The Bottom Line

AI coding tools are incredible for generating starting points. But they don't produce high quality code and can't teach you what good code looks like or how to improve it.

VibeCodeArena bridges that gap by providing:

✓ Objective analysis that shows you what's actually wrong
✓ Educational feedback that explains why it matters
✓ A "Challenge" system that turns learning into action
✓ Measurable improvement tracking so you know what works
✓ Competitive motivation through leaderboards

My "simple image carousel" taught me an important lesson: The real skill isn't generating code with AI. It's knowing how to evaluate it, improve it, and learn from the process.

The future of AI-assisted development isn't just about prompting better. It's about developing the judgment to make AI-generated code production-ready. That requires structured learning, objective feedback, and iterative improvement. And that's exactly what VibeCodeArena delivers.

Vibe Coding: Shaping the Future of Software

A New Era of Code

Vibe coding is a new method of using natural language prompts and AI tools to generate code. I have seen firsthand that this change makes software more accessible to everyone. In the past, being able to produce functional code was a strong advantage for developers. Today, when code is produced quickly through AI, the true value lies in designing, refining, and optimizing systems. Our role now goes beyond writing code; we must also ensure that our systems remain efficient and reliable.

From Machine Language to Natural Language

I recall the early days when every line of code was written manually. We progressed from machine language to high-level programming, and now we are beginning to interact with our tools using natural language. This development does not only increase speed but also changes how we approach problem solving. Product managers can now create working demos in hours instead of weeks, and founders have a clearer way of pitching their ideas with functional prototypes. It is important for us to rethink our role as developers and focus on architecture and system design rather than simply on typing c

Vibe Coding Difference

The Promise and the Pitfalls

I have experienced both sides of vibe coding. In cases where the goal was to build a quick prototype or a simple internal tool, AI-generated code provided impressive results. Teams have been able to test new ideas and validate concepts much faster. However, when it comes to more complex systems that require careful planning and attention to detail, the output from AI can be problematic. I have seen situations where AI produces large volumes of code that become difficult to manage without significant human intervention.

AI-powered coding tools like GitHub Copilot and AWS’s Q Developer have demonstrated significant productivity gains. For instance, at the National Australia Bank, it’s reported that half of the production code is generated by Q Developer, allowing developers to focus on higher-level problem-solving . Similarly, platforms like Lovable or Hostinger Horizons enable non-coders to build viable tech businesses using natural language prompts, contributing to a shift where AI-generated code reduces the need for large engineering teams. However, there are challenges. AI-generated code can sometimes be verbose or lack the architectural discipline required for complex systems. While AI can rapidly produce prototypes or simple utilities, building large-scale systems still necessitates experienced engineers to refine and optimize the code.​

The Economic Impact

The democratization of code generation is altering the economic landscape of software development. As AI tools become more prevalent, the value of average coding skills may diminish, potentially affecting salaries for entry-level positions. Conversely, developers who excel in system design, architecture, and optimization are likely to see increased demand and compensation.​
Seizing the Opportunity

Vibe coding is most beneficial in areas such as rapid prototyping and building simple applications or internal tools. It frees up valuable time that we can then invest in higher-level tasks such as system architecture, security, and user experience. When used in the right context, AI becomes a helpful partner that accelerates the development process without replacing the need for skilled engineers.

This is revolutionizing our craft, much like the shift from machine language to assembly to high-level languages did in the past. AI can churn out code at lightning speed, but remember, “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” Use AI for rapid prototyping, but it’s your expertise that transforms raw output into robust, scalable software. By honing our skills in design and architecture, we ensure our work remains impactful and enduring. Let’s continue to learn, adapt, and build software that stands the test of time.​
