What I'm looking for

I’m looking for a team where I can own React Native architecture end-to-end, ship high-performance features, collaborate closely with product stakeholders, and build reliable mobile experiences with real user impact.

I’m a Senior React Native engineer with 5+ years of experience building and scaling production mobile applications across workforce management, healthcare, and e-commerce.

At ReadyOn, I architected and delivered onboarding, scheduling, and workforce management features used by 40,000+ daily active users across employer and worker platforms, while serving frontline workforce management for hiring, onboarding, scheduling, shift management, and real-time engagement.

I improved mobile accessibility through VoiceOver (iOS) and TalkBack (Android) support, and reduced initial load time by 50%. I also managed OTA updates using Expo EAS Update to deploy bug fixes and feature releases without requiring App Store or Play Store approval.

I lead from requirements to production release—owning build distribution (dev/staging/production) with Expo EAS and coordinating key technical decisions with stakeholders. I’ve optimized responsiveness and memory usage using Redux Toolkit, RTKQuery, query caching, efficient list rendering, component optimization, and code-splitting, and I continuously improve stability with proactive bug fixing and monitoring (Sentry/Fullstory).
