概要
Master backend architecture by implementing industry-standard patterns like Clean Architecture, Hexagonal Architecture (Ports and Adapters), and Domain-Driven Design. This skill provides structural guidance for decoupling business logic from infrastructure, enabling you to build systems that are highly testable, technology-agnostic, and easy to maintain. Whether you are architecting a new microservice or refactoring a legacy monolith, it offers the templates, directory structures, and strategic principles needed to manage complex domain logic and establish clear system boundaries.
