Senior Fullstack Engineer with 6+ years building scalable web & mobile products across Fintech, GovTech & Web3 — shipped to 2M+ people on 4 continents. Now AI-augmented, compressing months of work into days.
Engineer who ships products, not just code.
I build full-stack systems end to end — designing RESTful APIs and backend services, then translating high-fidelity designs into pixel-perfect, performant UIs. My core stack is Node.js, Next.js, TypeScript, React and React Native, with a strong emphasis on Test-Driven Development, clean architecture and reliability.
I've shipped a cooperative financial platform targeting 2,000+ cooperatives with an integrated payment gateway, a government inspection system for Rwanda's RICA, a US-based Web3 community platform, and live consumer apps on the Play Store. Recently I built and self-deployed five production applications — the ones below — on infrastructure I run myself.
A decade-shaped journey across 4 continents.
