About

I build STUFF. Backend by instinct. Frontend when needed. Designer when no one's looking.
I make agents write code that scales, ships, and doesn't embarrass me.
Yes, I do care about perfectionism and real-life usability.
Also a professional video editor, freelancer and post productionist with 8YOE, which prolly explains why my UI looks sexy.

Previously

A professional freelance video editor, MT6785 android kernel QA, EDM producer

Currently

Leaning agentic harness engineering, a full time student, a cracked dev, a movie maniac and a part-time gamer (yes I game on a mac)
