BIO
I’m the Co-Founder and CTO of Boom, where I lead our AI efforts and tackle the hardest technical problems behind the product. Before Boom, I was the first engineer at Atrato (YC W21), helping scale a BNPL platform that processed millions in loan applications each month. I hold a double major in Mechatronics (ITESM) and Automation (Hochschule Esslingen). I focus on practical AI that drives business results. I also do hackathons for fun and have won six recently. Outside work I code side projects
