Thesis

Backend and AI-native plumbing — real-time voice systems, multimodal AI workflows, and the production backends that make them work. Plus a kernel and a game engine, because I like knowing how things work underneath.

Graduating May 2026 — open to full-time across AI workflow, voice, and full-stack product roles.

About this site

Hand-written HTML, CSS, and JavaScript — zero dependencies. Set in Fraunces and JetBrains Mono on a warm paper palette with a rust accent. Light and dark modes with a circle-wipe view transition.

There are a few easter eggs. Press / or ? to open the terminal. Try help. The Konami code does something. Tapping the portrait a few times does something else.
