Hexagonal Architecture (Ports & Adapters)
Architects maintainable, testable software systems by decoupling core business logic from external frameworks and infrastructure.
Hexagonal Architecture (also known as Ports and Adapters) is a design pattern that isolates core business logic from infrastructure, transport, and persistence details. This skill provides expert guidance for implementing clear domain boundaries, dependency inversion, and testable use-case orchestration across TypeScript, Java, Kotlin, and Go. By following these patterns, developers can build future-proof services where frameworks can be swapped, databases replaced, and multiple interfaces supported without rewriting central business rules. It includes a specific migration playbook for refactoring legacy systems and detailed testing strategies for every architectural boundary.
