I’m a mobile engineer with 10+ years of experience building and shipping React Native apps for iOS and Android end-to-end, from requirements to App Store and Google Play deployment. I focus on reliability and resilience—especially in offline-first products—designing SQLite data layers and asynchronous sync workflows so my apps keep working when connectivity is limited. I also bring a systems-and-infrastructure mindset to software: I’ve supported mission-critical environments (including 911 dispatch, fire, and police systems) and used that discipline to improve debugging, defensive component architecture, and edge-case handling. Outside of mobile, I build REST API integrations, work across multiple environments with CI/CD (EAS Build/Updates), and collaborate closely with end users to iterate based on real field feedback.…I’m a mobile engineer with 10+ years of experience building and shipping React Native apps for iOS and Android end-to-end, from requirements to App Store and Google Play deployment.
