Background
I'm a 6th-semester Software Engineering student at the University of Cartagena, Colombia. I focus on frontend and full-stack development, building modular platforms like SkyVault and SelanFlow using React, TypeScript, Next.js, and Spring Boot.
Current Focus
I am deeply passionate about UI/UX design and crafting fluid interfaces. In my free time, I help fellow students by teaching a basic introductory course on Java and Spring Boot fundamentals. I'm always eager to learn, share knowledge, and take on new technical challenges.
