Born and raised in the Green Heart of Holland, I now live in the beautiful town of Wassenaar with my small family. I work in the city of the Hague as an Advisor at the Ministry of General Affairs, which is a beautiful bicycle ride away.

I have been building websites since 1996. My studies in Multimedia Design prepared me very well for working in the online world. Then I founded my own company, and later became a consultant. Working for and in small, medium, large and multinational business, I also gained a lot of experienced by working in government and semi-government organisations. When I started out I focused mainly on web standards, HTML writing and CSS. I got very good at those. And even won medal in a web design competition. Later I also branched out into other important linked areas like communication advice, content management, design, usability, accessibility, architecture and project management. Now I work at the Dutch Ministry of General Affairs, where I advice on website quality and security.


My hobbies have always been very visually oriented. I started building websites for fun, then moved on to photojournalism for a small local news outlet in 1999. Doing that for so many years made me fall in love with photography. More recently I got into DIY. If I'm not working on my house or playing with my son, you'll find me buried in a book.

The website

This website has existed in some form since 1996. It started out as a plaything on a server of the Economics faculty of the University of Amsterdam. Currently you're looking at revision 14 of the design. We've come a long way.

In its long life it has been a simple HTML2.0 site and a flash presentation. It once had a style switcher, and has been plain HTML until 2002. That's when the news system was first introduced. In 2004 it was one of the first websites to fully validate as XHTML 1.1. Applications like the photo albums were added, and some applications quickly died. Like the linklog and the blogroll. I like to keep development organic.

Currently the website is running on the latest version of WordPress. I built a custom theme, since I like semantics, performance and control over my own code. I'm using Gitlab to maintain my template code, with a runner configured to automatically publish changes to the website.
