Summary:

  • Integrate REST and GraphQL APIs; manage state with Redux Toolkit, Zustand, or React Query.
  • Implement push notifications, deep linking, in-app navigation, and offline-first strategies.
  • Write clean, well-tested code; maintain CI/CD pipelines using Fastlane, GitHub Actions, or Bitrise.
  • Collaborate with designers, backend engineers, and product managers in Agile sprints.
  • Conduct code reviews and mentor junior mobile developers.
