What specific patterns does this skill support?

It supports Clean Architecture, Hexagonal Architecture (Ports and Adapters), and Domain-Driven Design (DDD) principles for complex system design.

Can I use this for existing projects?

Yes, the skill is specifically designed to assist in refactoring existing legacy codebases into more maintainable, loosely coupled structures.

How does this improve software testing?

By separating core domain logic from infrastructure (like databases and external APIs), it allows you to easily mock dependencies and focus on unit testing business rules.

Is this skill limited to a specific programming language?

No. While implementation examples may use Python, the architectural principles and patterns provided are language-agnostic and apply to any backend stack including Node.js, Go, or Java.

API Development

Implements industry-standard architectural patterns like Clean Architecture, DDD, and Hexagonal design to build robust backend systems.

About

This skill empowers developers to transition from tightly coupled monolithic codebases to modular, maintainable, and testable architectures. By leveraging Clean Architecture, Hexagonal (Ports & Adapters) patterns, and Domain-Driven Design (DDD) principles, it provides structured templates and guidance for organizing business logic independently of external frameworks and databases. It is an essential tool for architecting new microservices from scratch or refactoring legacy applications to improve long-term scalability and code quality.
