  • Solid hands-on experience with React Native using TypeScript, hooks, React Navigation, and state management frameworks (Redux Toolkit, Zustand, or MobX).
  • Practical experience driving brownfield/strangler-fig migrations or modernizing legacy mobile apps.
  • Strong background in backend integration via REST APIs, JWT, and OAuth2/OIDC protocols (experience with AWS Cognito is a big plus).
  • Proficiency in offline-first engineering using local storage engines (SQLite, Realm, AsyncStorage, or MMKV) and data synchronization queues.
  • Experience setting up mobile CI/CD automation and build pipelines (Fastlane, GitHub Actions, Bitrise, or CircleCI), including code signing and distribution.
  • Solid testing practices utilizing Jest, React Native Testing Library, and optionally automated E2E tools like Detox or Appium.
