Clean architecture structures scalable backends by defining clear boundaries and dependency rules, separating core domain logic from external interfaces. This skill codifies those principles to help organize maintainable codebases with adaptable interfaces.

Applying domain-driven design during refactors involves defining bounded contexts and isolating domain logic. This skill provides decision criteria and templates to guide boundaries, dependencies, and implementation strategies for restructuring complex codebases.

Hexagonal architecture is used when you need adaptable ports and adapters to isolate core logic from external systems. This skill explains the trade-offs between hexagonal, clean, and domain-driven design patterns to help you choose the right approach.

Organize backend codebases by mapping bounded contexts to directory structures and implementing ports and adapters for external dependencies. This skill provides recommended directory layouts and governance guidance to accelerate adoption.

Yes, this architecture guidance applies to new project design, large-scale refactors, and architecture governance. It offers templates and decision criteria to define boundaries, dependencies, and interfaces across various backend development stages.
