About me
I’m Gar, a technical product leader with 15 years of experience shipping developer platforms, financial infrastructure, and AI-powered workflows.
Founding PM, venture-backed CEO, zero-to-one builder across fintech, web3, and healthtech.
Right now I’m obsessed with using genAI to help scrappy teams punch far above their weight with better systems, cleaner processes, 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.
