About me

Hi, I'm Gustavo, a backend-focused developer from Brazil. I build backend systems using Node.js, Python and relational databases, focusing on clean architecture, API development and real-world problem solving. I enjoy creating practical projects to deeply understand how systems work behind the scenes — from database design to business logic and data consistency. Currently, I'm focused on improving my skills in Node.js, TypeScript, SQL and REST APIs, aiming to become a professional backend developer.
