What I'm looking for

I'm looking to own complex mobile, web, and backend work end-to-end, from architecture and modernization through release, performance optimization, and production support.

I've built and modernized React Native, React, and backend products across logistics, fintech, healthcare, tourism, CRM, and HR. At Brightech, I progressed from React Native Engineer to Mobile Team Lead and Backend Engineer while working across multiple logistics products.

For Dispatchland, I transformed a stateless proxy into a distributed backend platform using Bun, ElysiaJS, Node.js, PostgreSQL, and Redis. I replaced direct mobile communication with 40+ legacy TMS APIs through a unified gateway and supported real-time workloads of roughly 10k concurrent drivers.

I also led React Native architecture modernization, New Architecture migration, shared-codebase work, custom OTA delivery, and offline-aware fleet workflows. More recently, I upgraded legacy React Native applications, moved React applications from CRA/CRACO to Vite, and integrated AI-powered search across mobile, web, and admin products.

In open source, I maintain production-used React Native libraries and created Zig-powered hashing libraries for React Native and Flutter. My industrial automation background continues to shape how I approach low-level systems, performance, and pragmatic product delivery.
