Odisei Play
Odisei Play is the companion app for the Travel Sax, an electronic saxophone. Video courses, play-along songs, and practice tools that react live to what you play, streamed from the instrument over Bluetooth MIDI. One React Native codebase, three platforms: iOS, Android, and web. I joined as Lead React Native Engineer in 2024, pairing with the CTO in a two-engineer team. Since then, close to half of the commits in the repo are mine.
