I build clear tools
for real questions.
I'm Keith, a developer who turns messy questions into usable interfaces and dependable systems. I work especially well where data, sport, and security meet, and I photograph the details I notice along the way.

Pentesting Homelab
I built a multi-machine lab to understand how offensive security techniques work in practice, from post-exploitation and network pivoting to Pass-the-Hash and cracking workflows.
Personal Website
I built this site as a fast home for projects and photography, with a Cloudinary-backed gallery that lets me publish new images without changing the app.
