Mobile & web engineer
Updated 6 August 2026
I build iOS apps and web apps.
Most of my time goes to Tandem, where a client and a developer follow the same project in one place. The rest goes to Yam's, a score sheet for the dice game. It has an App Clip, so someone can join a game without installing anything.
I spent four months at Nightborn for my end-of-studies internship, on two client apps: one for a retail chain, one for weddings. My part was mostly how they feel. Animations, haptics, launch screens. The work that starts once the app already runs.
I am looking for mobile and web work, in Belgium or remote. Get in touch.
