What I'm looking for

I’m looking for a senior mobile role where I can own architecture and performance, build cross-platform products with React Native (and iOS/Android), integrate cloud messaging securely, and mentor teams while shipping production apps end-to-end.

I’m a Senior Mobile Application Developer with 9+ years of mobile experience and 6+ years focused on React Native. I’ve shipped 20+ production apps across healthcare, fintech, and e-learning, taking ownership from architecture through end-to-end release.

I lead mobile architecture decisions for 5+ cross-platform React Native apps, and I’ve mentored a team of 2–3 junior developers through code reviews and production release coordination. My work emphasizes performance optimization and reliable cross-platform behavior using React Native performance tools and advanced module patterns.

I build secure, scalable mobile solutions—integrating REST APIs, AWS services, Firebase messaging, and native functionality through TurboModules/NativeModules and native bridging. I’m comfortable shipping via App Store and Google Play Console, troubleshooting crashes and bugs, and delivering mobile features using Redux-based state management, OTP onboarding flows, and real-time experiences like telehealth and virtual care.
