      <guid>https://dev.to/sanvi_udhan_97ee4c4b862d5/i-built-a-tool-that-tells-you-what-kind-of-developer-you-are-repolens-4c01</guid>
      <description>&lt;h2&gt;
  
  
  What I built
&lt;/h2&gt;

&lt;p&gt;RepoLens analyzes any GitHub profile or repository and generates a full developer intelligence report.&lt;/p&gt;

&lt;p&gt;🔗 Live: &lt;a href="https://repo-lens-ivory.vercel.app/" rel="noopener noreferrer"&gt;https://repo-lens-ivory.vercel.app/&lt;/a&gt;&lt;br&gt;
⭐ GitHub: &lt;a href="https://github.com/Sanu700/RepoLens" rel="noopener noreferrer"&gt;https://github.com/Sanu700/RepoLens&lt;/a&gt;&lt;/p&gt;

&lt;h2&gt;
  
  
  The idea
&lt;/h2&gt;

&lt;p&gt;GitHub profiles don't tell you much at a glance. Stars are vanity. The contribution graph is noisy. There's no easy way to understand a developer's style, consistency, or growth over time.&lt;/p&gt;

&lt;p&gt;So I built RepoLens.&lt;/p&gt;

&lt;h2&gt;
  
  
  What it does
&lt;/h2&gt;

&lt;p&gt;&lt;strong&gt;Profile Analysis:&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;🧠 Dev Persona — 6 personality types based on your coding patterns (The Architect, The Hacker, The Ghost, The Explorer, The Craftsman, The Collaborator)&lt;/li&gt;
&lt;li&gt;🎯 Skill Radar — scored across Productivity, Consistency, Community, Diversity, Documentation, Open Source&lt;/li&gt;
&lt;li&gt;📈 Career Timeline — year by year breakdown of repos, stars, languages&lt;/li&gt;
&lt;li&gt;🦉 Coding Habits — hour/day activity heatmaps, night owl detection&lt;/li&gt;
&lt;li&gt;💡 Personalized Suggestions — specific tips to improve your GitHub profile&lt;/li&gt;
&lt;li&gt;🃏 Shareable Card — download a PNG to post on LinkedIn/Twitter&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Repo Analysis:&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Productivity score 0-100&lt;/li&gt;
&lt;li&gt;Commit activity charts&lt;/li&gt;
&lt;li&gt;Language distribution&lt;/li&gt;
&lt;li&gt;Smart insights + improvement suggestions&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;
  
  
  Tech Stack
&lt;/h2&gt;

&lt;ul&gt;
&lt;li&gt;Frontend: React 18 + Recharts&lt;/li&gt;
&lt;li&gt;Backend: Node.js + Express&lt;/li&gt;
&lt;li&gt;Data: GitHub REST API&lt;/li&gt;
&lt;li&gt;Hosting: Vercel + Render&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;
  
  
  What I learned
&lt;/h2&gt;

&lt;p&gt;The hardest part was the persona detection engine — mapping GitHub activity signals to real developer archetypes. Commit timing, language diversity, repo count, documentation scores all feed into a scoring function.&lt;/p&gt;

&lt;h2&gt;
  
  
  Try it
&lt;/h2&gt;

&lt;p&gt;👉 &lt;a href="https://repo-lens-ivory.vercel.app/" rel="noopener noreferrer"&gt;https://repo-lens-ivory.vercel.app/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Drop your persona in the comments — I'm reading every single one! 👇&lt;/p&gt;

&lt;h2&gt;
  
  
  One small ask
&lt;/h2&gt;

&lt;p&gt;If RepoLens was useful — an ⭐ on GitHub helps it get discovered by more developers. Takes 2 seconds 🙏&lt;/p&gt;
