About me
I'm Gar, a technical product leader with 15 years of shipping developer platforms, financial primitives, and AI-powered workflows.
Founding PM, venture-backed CEO, zero-to-one builder across fintech, crypto, and healthtech.
Right now I'm obsessed with using GenAI to turn scrappy teams into ones that punch far above their weight with better systems, cleaner process, and the kind of velocity that makes a quarter feel like a year. I'm actively building and prototyping in this space, and most weeks you'll find me tearing apart a workflow to see what an agent, a well-placed API, or a smarter primitive could do in its place.
