Founder & Engineer
breakouts.trade
Berkeley, CA
Founder and sole engineer of breakouts.trade: a browser drill app and daily scanner for a breakout trading strategy, and the Python research engine and live execution robot behind it, all as the repositories' only contributor.
Key Achievements
- ▸Built a browser drill app for breakout patterns and a daily scanner on the same strategy code: 458 signups, ~240 activated users, 10,203 practice drills
- ▸Reviewed all 67 API route handlers and middleware in June 2026, found a credentials path that accepted a password as proof of Google identity, and fixed and re-verified it
- ▸Hand-wrote 22 idempotent SQL migrations and 13 row-level-security policies with no ORM, and gated every pull request on type-check, lint, tests and build
- ▸Replaced a stock-metadata cold path that fanned out ~18,000 storage reads and timed out on every cold start with one precomputed artifact, and added a test that proves the fan-out is gone
- ▸Shipped an Interactive Brokers robot that has traded real money since June 2026: systemd units, a kill switch, broker-versus-journal reconciliation every five minutes and a heartbeat that names the running commit
- ▸Backtested 66,753 trades, 1998–2026, survivorship-free, and ran the 2024–2026 holdout once at mean R = 2.61
