Hello, my name is Jaimy de Graaf

I’m a freelancer specialized in data-driven applications.

I have experience with PHP, Javascript and HTML/CSS. I use a ton of open source tools like jQuery, Node.js and content mangement systems including Wordpress, Magento. But I'll admit I rather build a tailored-made CMS.
