This skill provides a comprehensive blueprint for building scalable, maintainable Python backends using FastAPI. It bridges the gap between simple tutorials and complex production requirements by offering standardized patterns for async database operations with SQLAlchemy, secure JWT authentication, and a clean separation of concerns via a transactional service layer. Whether you are starting a new project or refactoring an existing one, this skill ensures best practices in data validation, error handling, and automated testing are followed from the outset.
