Senior Fullstack Engineer

I’m a Full-Stack Engineer who enjoys building products end-to-end and turning complex ideas into simple, reliable user experiences.

I was a co-founder at AITR, where I’ve taken full ownership of the frontend, working closely on everything from product decisions to implementation and performance.

Before that, I co-founded Stocks IR, a platform focused on automating tax calculations for Brazilian B3 investors. I worked on the mobile app and deployment CI/CD, building the core tax logic and helping secure an official contract with B3. This app has been launched to Google Play Store but is not live anymore.

Over the past 3+ years, I’ve worked remotely from Brazil with teams in Italy and the United States. This experience helped me get comfortable collaborating across different cultures and time zones while delivering production-ready systems.

I’ve also worked extensively with financial and banking APIs like Treasury Prime, Plaid, QuickBooks, Gusto, and Ramp, building integrations for payments, payroll, accounting, and financial operations.

I’m most comfortable owning features from idea to production, and I care a lot about writing clean code, building scalable systems, and creating products that people actually enjoy using.
