FastAPI Clean Architecture

概要

FastAPI Clean Architecture provides a comprehensive framework for developing robust Python backend services inspired by enterprise financial systems. By enforcing a strict three-layer separation—API, Domain, and Infrastructure—it ensures that business logic remains framework-agnostic and highly testable. This skill guides developers through implementing advanced patterns like dependency injection, the repository pattern, and domain-driven design, making it an essential companion for building scalable applications that require long-term maintainability and seamless integration with multiple data sources.
