At Open Studio Network LLC, I lead development of Josephine (Open Studio Jazz), a cross-platform jazz education app for web, iOS, and Android. I built and shipped features including a lesson video player, course dashboard, skill pathways, and live sessions.

I work across the client and backend, using Supabase for PostgreSQL RPC functions, migrations, row-level security policies, and edge functions. I also implemented WordPress–Supabase SSO to support migration from the legacy platform without disrupting existing users.

Earlier, at RITECH INTERNATIONAL AG and HYBRIDVALLEY, I led development of Android and iOS projects and React and React Native applications. My project work includes published apps such as Guac App, Sal's Mobile, and Urban Traffic App.
