I build products: I figure out what’s worth building, then build it properly, from the first sketch to the thing people use. Right now that’s Timeless, and until recently Choiz. Before that, two years on web3 platforms at Shiba Inu, freelance work for clients, and a few products of my own, including one I shut down after launch because I hadn’t checked whether anyone wanted it.
