After years of working from the comfort of Python and Django, I moved to the wild asynchronous world of FastAPI to improve latency in web-based AI applications. I started with FastAPI and built an open-source stack called FastOpp, which adds command-line and web tools similar to Django.

Initially, things went smoothly using SQLite and aiosqlite to add AsyncIO to SQLite. I used SQLAlchemy as my Object Relational Mapper (ORM) and Alembic as the database migration tool. Everything seemed to work easily, so I added a Python script to make things similar to Django’s migrate.py.
