My name is Jaap. I live in Nijmegen in the Netherlands (Holanda, los Paises Bajos). I am a freelance journalist, writing teacher and web developer. I usually write about economy, science and technology (i.e. 3D-printers, self-driving cars).
As a hobby, I made Twisst, a Twitter app that sends people an alert when they can see the international space station fly by at their location. @twisst is followed by 53.000 users in more than 160 countries.
Hope to meet you sometime!
