Cool. I'm also working on various side projects myself now too. Originally I thought would be in the general area near your -1- and -2-, but ended up finding myself spending my time learning general devops and web dev for the first time. I've worked on something like -1- before, but felt it would take too long to put together without the backing of a large amount of funding for data collection/generation and some collaborators as I'm a generalist.

I think I'll eventually get to ML CI, whether as part of a startup, or back in regular employee life.
