I'm Danilo, a product builder and Groselia co-founder based in São Paulo, with hands-on experience designing, building and shipping AI products for real customers. I combine product and brand design, full-stack development and customer discovery with data analysis at Brex and enterprise product prototyping at IBM.

My first job, in customer service at Sabesp, paid for my tuition. At IBM Client Engineering I ran discovery with enterprise clients across Brazil and Latin America and turned what we heard into watsonx prototypes and working demos in 4 to 8 week engagements. At Brex I learned how money actually moves: I dug into payment operations with SQL and Python, turned exceptions into requirements for Product and Engineering, and built a GPT-4 Slack summarizer that was showcased at an internal All-Hands.

Groselia is where it all comes together: a two-person team, no playbook, and a platform I designed and built from the database up.
