Biography

I am a founder and CEO with more than 15 years of experience building companies, products, and teams from the ground up.

My work sits at the intersection of payments, commerce infrastructure, and company building. I take a systems-first approach to solving complex problems, designing scalable foundations that help businesses grow without adding unnecessary complexity.

Over the course of my career, I have founded companies, led global teams, developed patented technologies and products, and helped some of the world's largest organizations modernize how they move money.

Today, I lead Gr4vy, a fully remote company helping enterprise merchants and ISOs take control of their payment strategy through orchestration, automation, agentic commerce, and infrastructure built for scale.
