Things I like to experiment with and build for fun. Each links to a full write-up, and to a live demo where there is one.
Nutmeg — World Cup Result Predictor
A soccer Elo model that runs entirely in your browser: pick any two nations for live odds, or play out the rest of the 2026 World Cup 20,000 times. Built to test whether a simple model can beat the bookmaker's closing line — it can't, and that's the interesting part.
SOXL Algorithmic Trading System
An automated trader for a 3x leveraged ETF, built for the ways it fails. Position state comes from the broker rather than memory, and a duplicate alert can't double a position. Three environments run side by side, a test instance round-trips a real order every 30 minutes as a health check, and every fill and error lands in a Telegram channel labeled by environment. A /panic command liquidates from a phone. Validation across 400 configurations then put the strategy's edge at zero.
