engineering Brian Schwind

Brian is a programmer, hacker, and hobbyist who moves seamlessly between the worlds of software and hardware. In his own words: “Software is always fun to write, but sometimes you just want to hold something you can give to other people and say I made that.” He brings extensive experience in Rust (tonari’s language of choice), and a can-do attitude and ability to make anything happen.
