I’m Wander Hillen, I’m a software developer, runner and former military officer currently living in Almere, near Amsterdam in the Netherlands. I am available for freelance backend work, specialising in optimalisation and scalability. This is my blog, where I ruminate about software, document neat tricks (partly so I can easily find them again myself!) and generally ponder about the world.

You can find my Github account over here. I also sometimes speak at various conferences, some of which will upload videos of me to youtube. The quickest way to reach me is probably via email, at wjw.hillen@gmail.com.
