Ask HN: How can a new back end dev start contributing to real-world open source?

Hi HN,

I’ve been learning backend development using Python and FastAPI. I’ve built small projects with JWT authentication (including refresh tokens), basic WebSocket messaging, and REST APIs.

I’d like to start contributing to real-world open-source projects in a way that’s actually useful to maintainers.

Any advice or pointers on where to start?

Thanks!
