I build at the intersection of math, business, and software. I write about craft in the information age at Contraption Company. In the past, I made Find AI, Booklet, FRCTNL, Booklet, Postcard, Moonlight, Staffjoy, and some other things. I'm a former digital nomad based in San Francisco. I'm curious about coffee, craftsmanship, fermentation, travel, and urbanism.
