Difficult realization that we're financially at our limit. I need work yesterday to support my wife and I. At this point, anything goes. Full time, part time, you pay and I code for you.

I am looking for a full-time job.
Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me.
If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂
