At Ludium, I developed MEC ENEM in collaboration with Brazil’s Ministry of Education to help students prepare for the national ENEM exam. The app is used by thousands of students and has a rating above 4.7 on major app stores.

I also developed MEC Idiomas with MEC, using React Native for mobile and C# for the backend to support students studying English, Spanish, and Portuguese. I apply AI-assisted development workflows to implementation, debugging, and refactoring, reviewing generated code for correctness and maintainability.

Previously, at Tupinambá Energia, I developed a queue management system for electric vehicle chargers that impacted over 30,000 users and increased the active user base by 47%. My work has also included a BYD infotainment app, backend features with Node.js and MongoDB, and management dashboards.
