I’m a composer who builds the systems that decide how musicians get paid. The big things are ONCE and OpenPlay, plus whatever else ends up below.

Currently building

ONCE

A pay-per-use music distribution and registration platform with AI tools and transparent royalty tracking.

Everything else

Apps

Things I've built for others; that I can talk about.

Simple free tools

Small things I built and released for free. Use them, break them, tell me.

Music

Composer releases — songs, scores, and where to listen.

LinkedIn
