Portrait of Daniel Park

New York, NY

Hi, I'm Dan.

Backend engineer and CTO of Furitos, building AI agents and cloud-native systems.

I'm a backend engineer who solves business problems with technology. Over the last decade I've built cloud-native systems at Amazon and Venmo, led architecture at a MarTech company, and founded Instaresy, a booking-automation product with 1,000+ paying users. I'm also CTO of Furitos, where I built Furi, an AI agent that lets pet-service businesses run everything through chat.
