I’m a React Native Developer with 3+ years of experience building production-scale mobile applications deployed on Google Play Store. I focus on performance optimization, stable releases, and user engagement—so the apps feel fast, reliable, and polished.

In my recent role, I developed scalable React Native apps and strengthened state management with Redux Toolkit to reduce crashes and improve response time. I integrated Firebase services like Push Notifications and Analytics, led code reviews to enforce clean architecture, and optimized bundle size using code splitting, lazy loading, and asset optimization.

Previously, I built and maintained cross-platform iOS and Android apps using React Native in an Agile environment. I implemented Supabase integration, improved data fetching strategies, handled pixel-to-pixel ratio and responsive UI across devices, and performed thorough testing and debugging to deliver bug-free releases.

My project work includes B2B and consumer app features—such as Firebase FCM push notifications, deep linking with assetlinks.json, Google Maps API integration, image upload optimizations, and cart synchronization with backend-stored data and full CRUD cart flows. I also take pride in deploying multiple applications to Google Play Store and continuously improving quality through performance profiling and code reviews.
