Zero Tests, Infinite Confidence
6 repos, 6 times HAS_TESTS=no. You have a Rubik's cube solver, a bird physics engine, AND an AI skill marketplace — but apparently writing a single unit test would break the vibe.
Burst Coder, Ghost Account
Weeks 1–13 of your heatmap are basically a graveyard, then you go full 4s in week 33 like you remembered GitHub existed. 784 commits but half the year is tumbleweeds.
soar.vercel.app: Born Yesterday, Already Deployed
You created soar on 2026-04-10 and pushed it live the same day. The commit history is literally 1 sample deep. Bold strategy — ship first, exist second.
Portfolio Outstars the Product
Your portfolio website (220 stars) has a CFOP cube solver, protein folding renderer, AND a D3 knowledge graph. At this point haileycheng.com is the most impressive project you've shipped.
91% Solo Artist
soloPct = 91. With 950 followers and 4544-star repo, you're somehow still a one-person band. The community shows up for you; you just never let them help.

website
Polished TypeScript portfolio featuring force-directed D3.js knowledge graph, integrated GitHub contributions, protein folding visualizations, and Rubik's cube solver with Next.js 14 and React Three Fiber.
heilcheng /
charytype
Polished typing-practice app with dual music-integrated modes (Rhythm & Piano). Built in Next.js/TypeScript with structured audio (Tone.js), adaptive training (keybr-style), and 3D visuals (Three.js). Early-stage repo: 7 stars, 2 days old, ~60 commits, no CI/tests, but well-architected with typed code.

heilcheng
Personal portfolio website with interactive D3.js knowledge graph of repositories. Minimal scope, limited documentation beyond README profile, no real application output beyond the graph visualization itself.

Tier thresholds
▸ How the pipeline works
- 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.
- 02Triage.A small model reads every repo's file tree + README and picks the 20 files per repo that actually reveal how you code.
- 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.
- 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.
- 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.
