Architects maintainable, testable, and loosely coupled backend systems using Clean Architecture, Hexagonal Architecture, and Domain-Driven Design.

Backend Architecture Patterns empowers Claude Code to design and refactor enterprise-grade backend applications by enforcing proven architectural paradigms. It guides the separation of concerns across domain models, use cases, ports, and infrastructure adapters, preventing anemic domain models and framework lock-in. Whether structuring a new service from scratch, untangling a legacy monolith, or isolating business logic with dependency inversion, this skill delivers concrete directory structures, domain entities, value objects, and repository patterns for resilient software engineering.
