What experience do you have with different architectural styles and system schemes?

Experience with architectural styles and system schemes includes understanding and applying various approaches to organizing code and application components. For example:

• MVC (Model-View-Controller): separation of data, logic, and interface.
• MVVM (Model-View-ViewModel): often used in Flutter with providers or BLoC for state management.
• Clean Architecture: separation into layers with clear dependencies, facilitating testing and maintenance.
• BLoC (Business Logic Component): a state management pattern popular in Flutter.

In practice, I often use MVVM or BLoC in Flutter for state management and responsibility separation, which allows creating scalable and maintainable applications.
