Have you had experience working with principles and structure of clean architecture in projects?

Yes, experience with principles and structure of clean architecture in projects allows creating more maintainable and scalable code. In Go, this usually means dividing the application into layers:

• Entities (business logic)
• Use Cases (interactors)
• Interface Adapters (handlers, repositories)
• Frameworks & Drivers (external dependencies, databases, UI)

This separation helps isolate business logic from implementation details, simplifies testing and component replacement. For example, interfaces are used for data access abstraction, making it easy to change the implementation without affecting the business logic.
