Projects.
An AI-native support platform. As a founding engineer I built a lot of it, including Discord support, the AI drafting, the help center, and the company website.
A project that lets a guest control a room they don't own by scanning a code and texting it. I designed the server and protocol behind it and tested it on real devices.
A project that sits between an AI coding agent and your computer and checks every action before it runs. I built it in Python to work with Cursor and Claude Code.
A project that attacks an AI support agent on purpose, finds where it breaks, and writes the rule to stop it. I built the whole thing myself, attacks to dashboard.
A project that recognizes who is typing from their keystroke rhythm instead of a password. I trained the typing model and built the check that flags a different typist.
A menu bar app that puts everything you need in one place, from tasks and classes to your job search. I built it myself, including turning messy notes into a plan.

About
Hi there! I'm Owen, a computer engineering student at the University of Washington. I like building things that people find useful.
This past summer I worked as a founding engineer at an AI support startup, where I shipped features and heard directly from customers about what was and wasn't working. On campus, I've also written flight software for a student satellite team.
Lately I've been spending most of my free time researching AI agents. I built Sentinel, which checks what coding agents are about to do and blocks anything dangerous (trying to expand to multi-task agents soon), and Tenant, which lets a guest text a room and have an agent control its physical devices.
My hobbies include playing basketball, practicing guitar, and going on hikes. I love picking up new activities that challenge me, and I'm always looking for the next thing to try.
