~/about
I'm Tim. I build things
and write about it.
Software engineer, open source maintainer, and occasional writer. I've been building things on the internet for 15+ years—startups, big companies, and everything in between.
I co-founded a company and took it public. Led engineering teams at Twitter. Shipped products used by millions. Made plenty of mistakes and learned from most of them.
These days I'm building Renumerate, maintaining open source tools under imothee.xyz, and writing tutorials about the things I learn.
