• Strong proficiency in Flutter and Dart.
• Experience with advanced State Management (BLoC, Riverpod, Provider, etc.).
• Solid understanding of REST API consumption and authentication mechanisms.
• Experience publishing apps to Google Play and the App Store.
• Proficiency in setting up and maintaining CI/CD pipelines (Fastlane, Codemagic, GitHub Actions).
• Strong Git skills and experience with GitFlow branching strategy.

Nice to Have:

• Familiarity with Firebase services (Firestore, Auth, Push Notifications, Crashlytics).
• Experience with GraphQL.
• Knowledge of automated testing frameworks: flutter_test, mockito, integration_test, patrol test.
• Experience developing custom plugins or native code integration (Swift/Kotlin).
