About me
Brazilian, with a degree in graphic design, I've worked in UX for over 10 years, at leading tech companies in Brazil, like Nubank and Wellhub, and in the United States, like Oppizi and Algemetric.
I've spent much of my career on products with complex business rules: credit, cybersecurity and business management. I connect research, data and design, from proven methods to AI-first processes.
Today I'm a Senior Product Designer at Wellhub, where I lead design for customer acquisition. I also created Bolona, a women's football prediction game I built with AI.
