Gabriel Taiwo

I’m a software engineer who’s built and shipped production fintech products end-to-end for 6+ years, spanning mobile (Flutter/Dart), backend (Firebase/Node.js), secure payments, and encrypted local data.

I take architect-level ownership from PRD to release with a spec-driven, AI-accelerated workflow that compresses delivery timelines without compromising security or quality—especially when shipping across real-world device and connectivity constraints.

In my recent roles, I delivered a real-time Flutter POS application with 1,000+ daily transactions, sped up transaction processing by ~30%, and built offline-first transaction workflows that reduced failed transactions during connectivity loss by 25%. I also integrated multiple OEM APIs and stabilized production by resolving ~40% of device-specific crashes across 15+ hardware variants.

I’ve also shipped wallet and trading experiences at scale—supporting 20,000+ active wallet users and 5,000+ monthly trading users—while strengthening security using JWT-based session management and delivering reliable, fast data flows via REST/GraphQL. I enjoy building secure SDKs and product foundations that teams can reuse confidently.
