Welcome to Gabriel's Website

About

I'm a Final Year Computer Science student at the National University of Singapore, passionate about leveraging technology to solve real-world problems.

With hands-on experience in distributed systems, database security, and AI-driven applications, I've led projects in both startup environments and established organizations. I thrive in collaborative teams, building scalable and secure systems to create meaningful impact. My work spans various industries, from disaster relief to education technology, and I’m always eager to tackle new challenges in software engineering and beyond.

Growth fuels me as I prize stepping beyond comfort zones and embracing transformative experiences. Education earns you a living, but personal development earns you a lifetime. I prioritize character development as much as technical aptitude as I've realized that an organization's true assets are its people.
