概要
The Backend Architecture Patterns skill empowers developers to build scalable, testable, and loosely coupled backend systems by providing deep guidance on proven structural paradigms. It offers concrete implementation patterns for Clean Architecture, Hexagonal Architecture (Ports and Adapters), and Domain-Driven Design (DDD). Whether you are bootstrapping a new microservice or refactoring a legacy monolith, this skill helps establish clear boundaries between business logic and infrastructure, ensuring your codebase remains resilient to technology changes and easy to unit test.
