02About

From Scratch to shipping.

Story
My programming journey started when I was 10 at CoderDojo in Rotterdam. I learned Scratch and Python under the mentorship of Felienne Hermans, which eventually led to me coaching and teaching other kids at CoderDojo Bibliotheek Maassluis. I later studied at Grafisch Lyceum Rotterdam, where I deepened my design and front-end skills while teaching myself mobile app development on the side, culminating in building and launching AntScout.
Philosophy
I don't claim to know everything, but I have a passion for building unique, custom things from scratch. I love the creative freedom of handling the entire stack, from UI/UX and client-side interactions to ML models and cloud backends.
Interests
Outside of coding, I'm usually at the gym, doing macro photography, experimenting with hardware (paired with 3D printing), or coding small personal projects just for fun.
