Spent a year of freetime catching up on everything and learning as much as possible, started sharing what I've found works or not, write a bunch of comments on HN and elsewhere, and have a email in your profile, eventually people will find you if you put out good stuff :)

Also bunch of past workplaces who've adopted AI in various ways who reach out once they find out what my current focus lies, but that's harder for others to replicate unless you've already had a career as a developer.
