I'm a Computer Science / IT student based in Iloilo, Philippines, with a passion for turning ideas into working software. I enjoy the full spectrum of web development — from writing clean backend logic to crafting intuitive front-end experiences.

My thesis project gave me hands-on experience building a complete web application from the ground up, navigating real technical challenges and shipping something that actually works.
