I'm an Information Systems Engineering student at the Universidad Nacional de Costa Rica, with a technical background in IT and networking. I focus primarily on backend development, but I'm comfortable working across the full stack — from REST APIs to cross-platform mobile apps and Oracle APEX business systems.
I enjoy writing clean, purposeful code and understanding the business logic behind each feature. I've worked on real-world academic and freelance projects, collaborated with dev teams, and I'm always looking to learn something new.
