02How I work

Database to interface

At Artevelde I studied programming, and graphic and digital media. I work on both sides of an app: the data model and the API on one side, the interface on the other.

I keep components small and consistent, reuse one set of colours and spacing, and build with accessibility in mind instead of adding it later.

Outside client work I build my own projects. This site is one of them: it's where I try out layout, motion and the three-language setup.

I like finishing a feature end to end, not stopping at the API.
