I'm a software engineer studying Computer Sciences and Mathematics at the University of Wisconsin–Madison. I enjoy building developer tools, educational software, full-stack applications, and large-scale game systems.

I've shipped production software for real clients, developed systems across Roblox experiences reaching 215M+ visits, and built products used by thousands of students.

A Little About Me

I like working across the full product stack: figuring out what should be built, designing how it should work, engineering the underlying systems, and getting it into the hands of real users.

A lot of my work has centered around software with real constraints: student planning systems, developer tooling, client products, marketplaces, and multiplayer game systems operating at meaningful scale.

Outside of software, I enjoy speedcubing, chess, teaching, and experimenting with new product ideas.
