Software development consultant (sling code and give advice about it), as the T. Rex of Codosaurus, LLC.

Mostly hacking Ruby the past several years, mostly C before that, lots of other stuff mixed in, professionally since 1983.

Slowly writing two books, one on my ACRUMEN definition of software quality (details at https://www.codosaur.us/ACRUMEN), and one for recruiters, on how to hire technical people.
