What I'm looking for

I’m looking for fully remote roles worldwide where I can lead React Native mobile architecture, build scalable networking and secure auth, optimize performance, and deliver polished RTL/i18n apps with strong CI/CD and release reliability.

I’m a Senior React Native Engineer with 5+ years of experience building and scaling high-performance cross-platform mobile applications for iOS and Android. I’ve delivered production apps used by 100K+ users across real estate, e-commerce, sports gaming, and loyalty, with a focus on TypeScript, Redux Toolkit, React Query, and clean architecture patterns.

In recent roles, I’ve led mobile architecture for sports gaming, designed scalable networking layers to reduce duplicate API code by 60%, and improved responsiveness by up to 35% through performance optimizations. I’ve also implemented secure JWT authentication with refresh tokens, integrated Firebase Crashlytics and FCM push notifications, and supported full RTL/i18n internationalization, collaborating in Agile/Scrum through sprint planning, estimations, and peer code reviews.
