What level of engineering solutions are you capable of developing and implementing?

At middle level and above, I am capable of developing and implementing engineering solutions that include:

• Architectural design of applications using patterns (MVVM, BLoC, Provider, etc.)
• UI and logic performance optimization
• Integration with REST API, WebSocket, databases
• Setting up CI/CD for Flutter projects
• Developing modular and integration tests
• Implementing custom widgets and animations to improve UX

For example, I can design an application with layered separation, where business logic is separated from UI, and implement efficient state management using Provider or Riverpod.
