About
I like shipping things people actually use.
I'm Gon — a computer scientist and founder. I started coding when I was 14; now I'm 23 and still love building things. While finishing my CS degree with honors, I co-founded and built the technology behind an AI workspace, a dating app that 15% of Harvard signed up for, and a marketplace where AI agents do real work.
Today I spend my time as co-founder and CTO of Grexal, designing the infrastructure that lets businesses hire AI agents the way they hire people — and lets developers get paid when their agents deliver.
