Interests

Apart from being a developer, I enjoy taking times outdoors. During the summer in Belgium, I enjoy hiking and having a nice apero. In the winter, I'm an avid skier.

When forced indoors, I follow a number of TV shows and read a lot of (sci-fi) books. I am also an aspiring chef: I love to cook!
Finally, I'm a bit of a gamer even though I'm now just a shadow of the younger me...
