About
I graduated with distinction from UCLouvain with a B.Sc. in Computer Science and a minor in management. I enjoy turning technical complexity into software that feels straightforward and dependable.
Outside of code, I manage a Linux home server, build PCs and stay active through running, badminton and table tennis. Chess keeps the problem-solving muscles warm.
