About

Portrait of Gregg Marayan
Taguig City, Metro Manila, Philippines

My journey began in a Senior High School robotics class, tinkering with microcontrollers and basic programming. That hands-on experience sparked the curiosity that led me to study Information Technology.

Since then I've grown through projects, coursework, an internship and community work with Google Developer Groups on Campus. I enjoy helping teams turn ideas into working software, whether that's chasing down a backend bug, refining a UI component or setting up a smoother team workflow.

Away from the keyboard you'll find me playing Tekken 8 and Surroundead, watching shows like Dexter, or trying out new frameworks and dev tools.
