How I Built a Production-Grade FastAPI Service Foundation

For my recent projects, I needed a FastAPI service that was secure, fast, and easy to maintain on Cloud Run. Instead of just using a template, I documented the deliberate architectural process.

The final foundation is a complete blueprint featuring structured logging (Structlog), asynchronous PostgreSQL (asyncpg), a clean Docker multi-stage build, and a powerful non-mocked testing strategy.

This post breaks down the FastAPI core and the trade-offs made to ensure the system is secure and scalable from Day One.
