I haven't done a ton of FOSS work lately, largely because... past a certain size of app it takes a lot of time.

But I helped with the Text Inputs feature on ESPHome, fixed some issues that made Armoria unable to work without a cloud CDN, worked on some bugs for CustomPiOs.

I've found lots of random bugs in Python libraries over the years.

I've also answered a lot of questions on Reddit, and made lots of bug reports.
