What I write about →

I'm Co-founder & CAIO (Chief AI Officer) at Celcoin.

I started coding at 14, in 1995. I built websites for beauty brands and shipping companies, plus an intranet for the University of São Paulo, back when the internet was still dial-up.

I spent 13 years at Catho, starting as a web designer and developer and leaving as CMO and B2C Sales Director. After that I was CMO and CTO at Oppa.

In 2016 I co-founded Celcoin. We started by turning small retailers into banking correspondents. Today we are financial infrastructure for fintechs and businesses, with more than 800 clients and eight acquisitions. At Celcoin I led marketing and brand, served as COO from 2019 to 2026, and now lead the company's AI agenda.

In 2026, Marcelo França and I were selected as Endeavor Entrepreneurs.

I also invest as an angel and mentor founders. In 2017 I wrote the book "Marketing e Gestão Postos à Prova" (in Portuguese).
