No this is an in-house tool. I would share the repo but for some reason it's private (not sure why, there's nothing confidential in it)

Got it, thanks. Well, if you ever decide to open it up I'd be keen to having a look at it. I have yet to see a good automated scheduler and none of the places I've been so far had an automated solution that worked fine when it comes to holidays, scheduled time off, etc. A lot of manual work was put into scheduling shifts, which I always found very disappointing.
