Profile

About

I'm a Computer Science student at CESAR School and my main interest is back-end. It's the part of the system that handles data, applies business rules and builds the integrations behind the interface; it doesn't show up on screen, but it's what holds up everything that does.

In my projects I've practiced this area with different stacks, depending on the problem: Java with Spring Boot for APIs, Python with Django for full applications, and C when I need more control over what is running. Front-end with React and TypeScript shows up when the delivery is the whole application, but it isn't where I focus my interest.

I like thinking about the system as a whole and about what happens after deployment: tested code, documentation and continuous integration are part of what I consider a complete delivery. This portfolio gathers part of that path, in team and individual projects.
