API Development

Streamlines Python backend development using FastAPI, Pydantic, and asyncpg through a rigorous 4-phase workflow and strict type safety.

This skill provides a specialized environment for high-stakes Python development, focusing on the FastAPI ecosystem and asynchronous patterns. It enforces a Domain-Driven Design (DDD) approach, strict Pydantic type-hinting, and a mandatory 'Red-Green-Refactor' testing cycle using pytest. By standardizing error handling, settings management, and database interactions with asyncpg and SQLAlchemy, it ensures production-grade code quality and maintainability for complex backend systems and data-intensive applications.

Key Features

01Strict Pydantic V2 implementation with separated Request/Response models
02Mandatory Red-Green-Refactor workflow using pytest and Ruff
03Advanced async hygiene and concurrent database query optimization
