To expand on #2, we are also open source, with our main app code at https://gitlab.com/upchieve/subway

Our long-term goal is to have engaging, fun feature work for community contributors to work on, and we do have those come up occasionally now, but we can use a lot of help just finishing our conversion of the backend to TypeScript, updating dependencies, small bug fixes and similar work, that we have issues ready for.

We also have a weekly tech community Zoom meeting that I'd be happy to send an invite for to anyone who emails me with interest. dave.sudia at upchieve dot org
