The first working implementation of a mutual cryptographic authentication system. Ty Everett designed the protocol on paper; I built the original production implementation, letting two parties prove who they are to each other directly, with no passwords and no third-party login. The IP was later acquired and open-sourced by the BSV Association, shipped in their TypeScript SDK as AuthFetch (client) and auth-express-middleware (server).

A college embedded-systems project that turned personal. A sensor rig that mounts to a compound bow, plugs into a computer, and measures how steady I hold at full draw, scoring each shot in real time so I could see my stability improve. I had shot a bow my whole life; this was the first time I instrumented it.

A full-stack interactive storytelling platform pairing illustration, animation, text, and sound. ASP.NET Core web app and REST API, a Xamarin.iOS client, Firebase, a custom .NET library, and a story state-management system I designed.
