I build software at TJX, study CS at Cornell Tech, aim to nail 25 dishes by 2027.
The cube follows along as you read. Each colour is a side of me, and whichever one you're on turns to face you. Turn the cube to jump to another side; twisting rows does nothing useful, it's just fun.

Cut Coach
A nutrition, lifting and body-weight tracker with an MCP connector, so Claude can read my logs and spot trends.
TypeScript · Expo · Next.js · Supabase · MCP
Headcount
Classroom attendance via QR codes that rotate every few seconds, so screenshotting it to the group chat doesn't work.
Python · FastAPI · Redis · Postgres · Docker · GitHub ↗
QK65 Mk3 Everything here was typed on it.
the PC · 9800X3D + 3080 FE Built it myself.
