Things I've built

Side project, live

Gear Finder

Pickup research for the guitar you already have.

Tell it what's in your guitar and what's bugging you, and it suggests pickups that fix it. It covers 1,365 pickups from 29 makers, and every spec links to its source. A TypeScript ingestion pipeline pulls specs, measurements, videos and prices from 15+ manufacturer and community sources into Postgres.

Bandmates

Find the people you were meant to play with.

A social network that matches musicians nearby by instrument, taste and ambition, with real-time private chat and video profiles. I led engineering: the matching algorithm, location queries in PostGIS, a type-safe tRPC API and a Socket.io chat server. It started as a Flutter mobile app. Performance work raised engagement 30%.
