About
I build web products end to end, with a soft spot for the front end. Two of the startups I worked at were acquired along the way.
Born and raised in Brazil, based in the Bay Area since 2022. I speak Portuguese, English and Spanish, plus a little German. Outside of work I'm doing a Master in Software Management at Carnegie Mellon, and I spent two years volunteering on the operations team of Brazil at Silicon Valley.
