💡 Learn how to design great software in 7 steps: https://arjan.codes/designguide.
In this video, we break down the anatomy of a scalable Python project using FastAPI and uv. You’ll learn how to set up a clean folder structure, manage configuration with .env, add centralized logging, and write simple but effective tests. We’ll also cover how to use pyproject.toml, .python-version, Docker, and docker-compose for consistent environments and easy onboarding.
