About01
I worked in finance long enough to know it wasn't for me. Taught myself to code, started building products, and never looked back.
That was more than a decade ago.
Since then, I've built products, led teams, started companies, and helped others build theirs. I care about craft, clear thinking, and working with people who give a damn.
