Product Manager at Nubank who launched a gamified credit-limit flow and optimized loyalty conversion through A/B tests.

Message

At Nubank, I launched a gamified progressive credit-limit flow designed to enable safer credit growth while lowering risk exposure. I also ran end-to-end A/B tests for the Mass Market loyalty program.

At Galena, I was the first Product Manager hired and helped build the product function from the ground up. I contributed to a strategic pivot to find the company’s place to win in the human development market.

At QuintoAndar, I worked on growth, lead management, and tenant acquisition, using user analysis and weekly A/B testing to improve the experience. My earlier work at Ambev included customer experience for Zé Delivery and innovation projects; I also took a sabbatical traveling across five continents.
