    Webdeveloper / Designer

    In 2007 I started working as a freelancer with a wide broad scope of interests. The project ranged from developing websites, to designing business cards and flyers... or even designing a calendar with one of my friends who works as a photographer. Over the years I started to develop iOS apps. You can see some of my work in the next section "Projects / Portfolio".

I'm always looking for new projects

I love the speed of the road, when it feels like you are flying through the landscape. But climbing up the mountains, being in the nature, with a moutainbike has its charm too.


Fitness is a good addition to cycling. It's a whole body workout and you are independant from any weather conditions. You can always push yourself to the limit.

Obstacle Races

An obstacle race is a combination of running and workout exercises. It makes much more fun than pure long distance running. Each obstacle has its own challenge and often you have to work together in teams to master an obstacle.
