What I'm looking for

I’m looking to build cross-platform mobile products where performance, reliability, and clear architecture matter. I want to own React Native features end-to-end, partner with UX/product, and deliver measurable user impact.

I’m a Senior React Native Developer focused on shipping reliable, user-centric mobile products with measurable impact. I architect and deliver config-driven features that let teams update content and roll out changes faster—without requiring app releases.

In my recent work, I redesigned and overhauled major product surfaces (Seller Pod and related flows), improving MAU and reducing friction through clearer journeys. I’ve also built operational and user-facing capabilities like real-time tracking, live notifications, and performance improvements that reduced app size and increased daily active users.

Across my projects, I combine strong React Native engineering with performance and monitoring discipline—crash/ANR monitoring, bundle and code splitting, and stability improvements. From healthcare telemedicine features (video, chat, vitals) to live inspection tracking, I deliver cross-platform solutions while partnering closely with UX/UI and product to turn complex requirements into polished experiences.
