MJ - FullStack Developer

Full-stack developer portfolio: 10 client systems shipped since 2022 for a university, a city government and small businesses. Each case study documents the architecture and trade-offs, such as offline-first sync, row-level security for role-based access, and a RAG backend kept separate from the mobile client (CharlieBot, Flutter and FastAPI). Peakle, my own pickleball product, is in public beta on React Native and Supabase. Most projects include a browser demo that runs on fictional data.
