Background

About Me

I'm a Computer Science student at Cesar School who discovered a passion for technology in high school. Since then, I've been continuously learning and applying my skills through academic, personal, and professional projects, always seeking opportunities to solve real-world problems through software.

Throughout my degree, I've worked on projects ranging from AI-powered applications for family farming to educational platforms, taking on both full-stack development and project management responsibilities. These experiences have strengthened not only my technical skills but also my ability to collaborate, communicate, and deliver solutions that create meaningful value for users.
