About
Production-Grade Mobile & Systems Engineering.
I’m Emmanuel O. (TOE Tech) — a Mobile & Systems Engineer shipping production-ready Flutter apps, real-time backends, and automated AI workflows.
I take full ownership from initial concept to store release.
Whether architecting offline-first Riverpod state engines, tuning Supabase and WebSockets for zero-latency sync, or configuring native iOS/Android builds, I bridge design polish with heavy backend engineering.
