I'm a Full Stack Developer based in Brazil, working with modern web technologies on both backend and frontend.

On the backend, I build secure APIs, real-time systems, authentication flows, background jobs and scalable services using Node.js and TypeScript.

On the frontend, I build complex dashboards, role-based systems, real-time interfaces, PDF reports, charts and responsive UIs, focused on performance, usability and maintainability.

I enjoy turning complex business rules into clean, well-structured and production-ready applications, from database to user interface.
