About Me
I began my journey in technology in 2018 when I enrolled in Information Systems at the Federal University of Santa Catarina, graduating in 2024. Since then, I've worn many hats—first as a technical support specialist, then as a full-stack developer, and today as a dedicated backend engineer. I'm passionate about programming because of the incredible things we can build and the constant challenges it brings. Over the years, I've honed my skills in API design, microservices, and clean architecture, and I thrive on learning new technologies every day and adapting quickly to change.
