I luckily got an interview at Behance because of my contributions to JSCS. I helped to merge it with ESLint and along the way discovered Babel and learned about "compilers". Now I get to spend about 50% of my time working on Babel at work. I am looking forward to the time when projects are able to work on OSS part/full time though!
Recently I gave some talks on what it's like to be a maintainer, how Babel is more than just the code itself, and dealing with burnout and the community. I did post I was going to spend less time on it to focus on health, so hopefully some people/companies will step up!
Ask me about OSS (its myths, its community, and its relationship to community/faith) or about the nature of Babel: it's difficult role in the ecosystem trying to glue it all together: spec compliancy with TC39, code speed/size complaints, JS fatigue, and handling it all as a group of volunteers.
