Hi there!
My name is Koen van Gilst and I'm a JavaScript developer who loves creating funny Twitter bots, educational games for my kids other creative stuff.
Have a look at my profile if you're interested in working with me or else feel free to browse through my experiments and projects below.
I also keep a blog here.
You can also find me on Github, LinkedIn and Twitter. Or send me an email.
