Structure a backend Clean Architecture project by separating entities, use cases, repositories, and adapters into distinct layers. This Skill provides directory structures and Python code examples to implement maintainable, testable backend systems.

Use Domain-Driven Design for complex business domains and Hexagonal Architecture for technology independence. This Skill guides selecting the appropriate backend architecture pattern based on your specific microservice requirements.

Clean Architecture and Hexagonal Architecture both isolate business logic, but Hexagonal focuses on technology independence via ports and adapters, while Clean emphasizes dependency inversion. This Skill explains core concepts and distinctions for backend development.

Implement repositories and adapters in Python by following the detailed code snippets provided by this Skill. It demonstrates writing entities, use cases, and adapters to facilitate scalable and maintainable complex backend systems.

Common software design pitfalls include improper dependency management and leaking domain logic. This Skill outlines best practices and challenges to avoid when applying Clean Architecture, Hexagonal Architecture, and DDD.
