I build things -> code, tools, instruments,
and, oddly enough, once turned a freezer into an ice bath.Started programming at 15 with Arduinos.Recently built a full blockchain data extraction app on top of an existing parser during my internship.Currently learning how to raise puppy and ship clean code.
Tech Projects
