de Gier

I design and build apps and websites end to end: the interface, the code, the machine learning and the backend that keeps it running.

AntScout

AntScout identifies ant species from photos with AI, and around that sits a species database with caresheets, interactive observation maps and nuptial flight predictions.

AntScout: A full ecosystem for ant keepers and myrmecologists, from a photo to a species name.

I started at ten, writing Scratch at CoderDojo Rotterdam.

Story
I learned Scratch and Python there. A few years later I was the one coaching kids, at CoderDojo Bibliotheek Maassluis. At Grafisch Lyceum Rotterdam I learned design and front end, and taught myself mobile development on the side. That side project became AntScout.
How I work
I like owning the whole thing: the screens people touch, the model that recognises an ant, the database behind it. I would rather build something specific from scratch than bend a template until it almost fits.
Off screen
Gym, macro photography (hence the ant), tinkering with hardware and 3D printing parts for it, and small projects that only exist because I wanted to see if they would work.
