I’m a casual contributor to nixos: I maintain a couple of smaller packages, and try to help out whenever I see something that can be improved with a package I’m interested in.
The complete list of “things to do” (issues, PR’s, hydra build failures) is pretty daunting, so I started on a small tool to make it easier to discover things I might want to help with, based on my interests:

It’s at a very early stage, but any feedback definitely welcome!
