Congrats! I appreciate this post because I want to be where you are in the not too distant future.

Contributing to Open Source can feel overwhelming, especially if working outside of one's primary field. Personally, I'm a scientist who got interested in open source via my academic interest in open science (such as the FAIR principles for scientific data management and stewardship, which are that data should be Findable, Accessible, Interoperable and Reusable). This got me interested in how scientists share code, which led me to the horrifying realisation that I was a better programmer than many of my peers (and I was mediocre)

Studying open source has been useful for seeing how big projects are managed, and I have been meaning to find a way to contribute (because as you show, programming skills aren't the only way to do that). It's cool to see posts like yours because it kicks my ass into gear a little.
