I'm Troy, a full-stack engineer at Cortucent Security, where I build and secure healthcare software that handles protected health information.

Off the clock I'm usually taking photos, playing guitar, drawing, making collages, or building websites for friends. I've also dabbled in lower-level projects in Zig and Rust, listed below.
