- Design clean navigation, deep linking, and mobile routing strategies (React Navigation, Expo Router).
- Implement secure authentication flows (OAuth/OIDC, biometrics, secure storage, token lifecycle management).
- Drive native module integrations (Swift, Kotlin) for SDKs such as payments, fraud detection, analytics, push notifications, and device security.
- Optimize mobile performance (startup time, bundle size, memory usage, rendering performance, offline caching).
- Establish CI/CD pipelines for mobile (Fastlane, EAS Build, App Store Connect, Google Play Console).
- Lead app release management, versioning strategy, and store compliance.
- Ensure adherence to mobile security best practices, privacy compliance, and accessibility standards.
- Partner with backend teams to define API contracts and optimize mobile-backend interactions.
- Champion automated testing (Jest, React Native Testing Library, Detox) and code quality standards.
- Mentor engineers and foster a culture of ownership, craftsmanship, and continuous improvement.
- Participate in architecture reviews and roadmap planning for long-term mobile platform scalability.
