This is a great start, but I don't think we did a good job of communicating the expectations for structure... I added some comments about using a library to help with the cron job stuff and the only other big change is that I think we should move the entirety of that endpoint out into utility functions and not expose them to the API. By that I mean we should probably have api/src/utils/github files for each of the major commands, each with just the interfaces that relate to what they do, and then we should have a function within a new root level file (maybe something like src/cronJobs.ts) that exports a single startCronJobs method you call from index.ts.

Let me know if you have any questions on the above; we can always hop on a call to chat. Beyond that, please don't write any more tests until we do another review of the cron stuff, just because I'm worried we'll need a few more rounds of revisions given the complexity of all this 😬

Overall looks good to me, with just some small nit-picky changes for better clarity.

LGTM 🚀

Getting close! Awesome work; just a few more tweaks and then we can work on testing.
