Two repos, one competition
prosperity-visualizer and prosperity-visualiser are basically the same IMC Prosperity dashboard committed to two separate repos within days of each other. Forking yourself is a bold strategy.
Heatmap goes brrr... then stops
40+ weeks of complete inactivity on the public heatmap, then a desperate flurry of commits in the final 10 weeks. This is what a deadline looks like from space.
Tests? Never heard of them
5 repos, 0 test suites, 0 CI pipelines, 0 licenses. test_gpu_benchmark.py in icw doesn't count — that's just a print statement with aspirations.
Solo 100%, community 0%
soloPct = 100, totalPRsYear = 0, totalIssuesYear = 0. Three followers — one of whom is probably yourself from a different browser tab.
Jupyter Notebook: 56% of your identity
More than half your public codebase is .ipynb files, most of which appear to be coursework handed to you with blanks to fill in. That's not a portfolio, that's a submission portal.

Zoral
Shadows one worker for a week, then takes over their job with zero extra setup. Behaves exactly like the original.

prosperity-visualizer
Specialized in-browser analytics dashboard for IMC Prosperity trading competition. Untyped JavaScript frontend with structured architecture, real backtest pipeline, and 8 analysis tabs. 19 commits in 3 weeks, zero external adoption.
gsgill7 /
prosperity-visualiser
Specialized in-browser trading dashboard for IMC Prosperity competition. 606 KB codebase with multi-format log parsing (ZIP/JSON/.log), Plotly charts, backtest API, and demo trader. Created 2 days ago with 30 recent commits.
gsgill7 /
icw
GPU-accelerated 6-DOF structural dynamics simulator for tuned mass damper optimization. Python project with typed GPU code, clear structure, meaningful documentation. Solves 25M configurations using CuPy/cuSOLVER batching. No tests, no CI, no license. Impressive technical scope but experimental coursework artifact.
gsgill7 /
IDP
MicroPython AGV control system for a Cambridge IDP project. Features graph-based pathfinding, sensor fusion, and modular hardware abstraction, but lacks tests, CI, license, and type hints. ~83 KB codebase with 1 commit in <1 day.
gsgill7 /
gsgill7
Personal portfolio README for Cambridge engineering student with links to side projects (prosperity-visualizer, nuclear regulatory AI). Repo itself is just a profile page in Jupyter Notebook format; no executable content or standalone project.

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.
