I built an AI-powered developer portfolio generator from GitHub profiles

#github #portfolio #ai #webdev

Ever wondered what your GitHub profile actually says about you as a developer? I did, so I built gitboard.app — drop in any GitHub username and get an AI-generated portfolio with skill analysis, repo summaries, and a competitive score.

What it does

Enter any GitHub username
AI analyzes your public repos, languages, contribution patterns
Generates a clean portfolio page with:
- Professional overview
- Repo summaries with technical highlights
- Skill extraction with proficiency levels
- Language breakdown
- A score out of 100 across 5 categories: Impact, Consistency, Breadth, Quality, Community
You get ranked on a global leaderboard

Try it: gitboard.app

The scoring system

Every profile gets scored 0-100 and placed in a tier:

🏆 Legend (75+)
💎 Elite (60+)
🔥 Outstanding (45+)
⭐ Notable (30+)
🌱 Growing (<30)

The algorithm uses log scale so massive repos don't dominate — a well-maintained small project can score just as well as a mass-star repo. Categories are weighted: Impact (30), Consistency (25), Breadth (20), Quality (15), Community (10).

Tech stack

Next.js 16 (App Router)
PostgreSQL + Redis + Bull for queue-based generation
OpenAI gpt-4o-mini for repo analysis (~$0.0005 per profile)
Cloudflare Turnstile for bot protection
Traefik reverse proxy on a single VPS

Each portfolio costs less than a tenth of a cent to generate. The queue system handles bursts gracefully — your profile gets analyzed in ~10 seconds.

Why I built it

Recruiters and hiring managers often glance at GitHub profiles but don't have time to dig through repos. Developers know their work is good but don't have an easy way to showcase it beyond a pinned repos section.

gitboard bridges that gap — it gives you a shareable link (gitboard.app/yourusername) that tells your story as a developer.
