About me

I work across the whole stack — modern web apps with React, Next.js and Node.js, mobile apps with Flutter, and systems-level software in C: I've written a compiler from scratch and shipped a small educational operating system.

The security side is what keeps me up at night — penetration testing, hardening, and understanding how things break. I presented at CHES 2024.
