About

I'm a self taught developer, having released my first iPhone app when he was just 14yo. Dropped out of a Computer Engineering degree in Brazil after a brief time as a visiting Cognitive Sciences student at UC Berkeley in order to become a full time entrepreneur when I was 21 years old, seven years ago. With Cumbuca, I went through Y Combinator, raised Lightspeed first investment in Brazil, and became the youngest ever controller of a regulated entity in Brazil, having our Payment Institution license approved by the Central bank at just 24 years old. I'm also one of the founders of INIT, the National Open Finance Association of Brazil, becoming one of the most knowledgeable people on Pix and Open Finance in the country.
