Senior React Native Engineer delivering secure, high-performance mobile apps for regulated fintech and Web3 teams.
What I'm looking for
I’m a Senior React Native Engineer with 6+ years delivering production-grade iOS and Android apps across Fintech, Web3, and security-sensitive, regulated environments. I specialize in JWT-based authentication flows, secure token and session storage (Keychain/Keystore), and building offline-first experiences that stay reliable in real-world connectivity constraints.
I’ve led end-to-end feature ownership while improving performance (re-render reduction, FlatList/VirtualizedList tuning, profiling and crash analysis) and integrating REST APIs plus WebSocket real-time updates with backend contract alignment. I also automate CI/CD using Fastlane and GitHub Actions, mentor mobile developers through code reviews, and have led mobile teams of up to 8 engineers—always focused on secure coding practices, maintainable architecture, and compliance-aware delivery.
