OpenGiving
Live2025 – present
A marketplace where sellers route part of each sale to a fundraising campaign, running as a web app, an iOS app and an Android app on one API.

I build iOS apps and the backends behind them. Right now that mostly means OpenGiving, a marketplace running as a web app, an iOS app and an Android app on one API that I write all of.
M.S. Innovation Management & Entrepreneurship at Brown, May 2027. Before that, first engineering hire at DAERO Group in Boston, and a B.S. in Computer Engineering at Insper in São Paulo. Providence, Rhode Island.
