I build iOS apps.
The biggest thing I’ve built is 
, a
marketplace where part of every sale goes to a fundraising campaign. I wrote all
the code for it: web, iOS and Android apps, and the backend API they share.
I grew up in São Paulo . Currently, I am studying at Brown until May 2027, pursuing an MS in Entrepreneurship, and studying cybersecurity at Harvard (cross-registered in person). Before Brown I was the first engineering hire at , a construction software startup in Boston backed by . I spent ten months leading their iOS app dev, while also supporting the web, infra and backend work.
I got my B.Sc. in Computer Engineering at Insper. For my
capstone, I worked on multi-cloud security
monitoring for 
, a Brazilian payments company. Part of it was a Python tool that mapped how their AWS
resources connected and flagged anything open to the internet that shouldn’t be.
I was also on Insper Dynamics, a student team building rescue robots, for 2 years. We won
a Best in Class award for sensing at 
in
2022 ,
and one for exploration, the autonomous mapping test, in
2023 .
In early 2023 I became president of the university’s robotics club.
