Bio

I build production-grade mobile apps and the resilient backends behind them. React Native on the front; NestJS, PostgreSQL and GraphQL on the back. Currently leading engineering at Jumatechs.

01— About

✶ Manifesto

An engineer's work is half code, half judgement. I care about the judgement.

I ship things that work.
Under load, on flaky networks,
at 2am for a release.

I've spent the last seven years leading mobile and backend work across fintech, real estate, HR platforms and consumer apps. Currently Lead Engineer at Jumatechs, where I drive architecture across React Native and NestJS stacks, run CI/CD with GitHub Actions and Expo EAS, and mentor a small team of engineers.

Before that I led hybrid mobile development at Intellier, shipped cross-platform products at Brain Station 23, and built public-facing products like the Bangladesh RAB CMS. I lean on AI tools (Copilot, Cursor) the way a chef uses a sharp knife — to move faster without cutting corners.
