What I'm looking for

I’m looking for a team where I can build production-ready React Native apps end-to-end with Node.js backends—owning architecture, shipping fast, and improving reliability. Remote-friendly roles worldwide are a strong fit for me.

I’m a React Native engineer with 5 years shipping production apps for UK, US, and Nigerian companies. I work end-to-end—building React Native frontends that integrate cleanly with Node.js backends.

I’ve led and delivered across the full mobile lifecycle: establishing core app architecture, rebuilding navigation and module boundaries, and stabilizing live products under tight deadlines. As a former lead engineer, I owned architecture decisions and guided teams through delivery and code reviews.

My engineering impact shows up in measurable outcomes, from reducing list load/render times by 40% using FlashList migration to cutting screen time-to-interactivity by 70%. I’ve also reworked real-time rider tracking, boosting location accuracy from 30% to 90% and restoring reliable pickup-to-drop-off tracking.

I’m also deeply invested in reusable developer-first components—creator & maintainer of @devvie/bottom-sheet, an open-source React Native package with 41,000+ monthly downloads and 360+ GitHub stars. Whether it’s crypto workflows, non-custodial wallet security, or real-time map features, I aim for production-grade reliability and clear system design.
