Desert Heatmap

Your contribution graph looks like a seismograph during a very peaceful geological epoch — 48 commits scattered across 52 weeks, with 45+ weeks of pure silence. Even your most active week only hit 4.

Polyglot Museum Curator

Python, TypeScript, JavaScript, Go, Rust, Ruby — six languages represented, yet only 3 repos scored. You've collected every ingredient but left the kitchen empty for years.

Stale Repo Graveyard

An 89% stale repo ratio means nearly 9-in-10 of your 45 public repos haven't been touched in over 2 years. That's not a portfolio — it's a time capsule.

Solo Artist, Permanently

soloPct = 100%. Every single commit across every repo is yours alone. You've been coding in a sealed room since 2009 with zero collaborators and 6 PRs to show for an entire year.

Since 2009, Still Warming Up

Joined GitHub in April 2009 — that's 15+ years of account history resulting in 10 total stars and 48 commits in the last year. The warm-up phase has outlasted most developer careers.

▸ How the pipeline works
  1. 01Scrape.Pull every non-fork repo pushed in the last 90 days, plus your contribution calendar, followers, and language byte counts — straight from GitHub's REST & GraphQL APIs.
  2. 02Triage.A small model reads every repo's file tree + README and picks the 20 files per repo that actually reveal how you code.
  3. 03Grade each repo. All repos run in parallel through a fast scoring model that reads the picked files and rates each one independently on Impact, Quality, and Depth — with evidence citations.
  4. 04Aggregate. A larger reasoning model combines the per-repo scores with server-computed stats (heatmap, commit cadence, language entropy, follower count) to produce the 6-dimension profile score + roasts.
  5. 05Correct.Deterministic server-side checks enforce anchor-scale floors (e.g. a profile with 2,000+ public commits can't score 30 Consistency) and recompute the final verdict.

~90 seconds per profile, ~$0.25 in compute. Total of ~240 files read across your top-12 repos. One rating per GitHub account per day.

▸ Data sources & caveats
  • Heatmap & commit totals: GitHub GraphQL contributionsCollection — covers the last 365 days, includes private repos when the user has opted in (default).
  • Language %: byte totals across the top 30 owned non-fork repos.
  • Curve: a small upward nudge centered on raw score ≈ 70, capping at 100. Prevents specialists from being unfairly penalised for narrow breadth.
  • Anchor corrections: when server-measured signals (e.g. privateWorkLikely, multiRepoVolume, follower count) mandate a minimum category score, the aggregation step enforces it. These are signal-conditional, not identity-based floors.
