    Drupal / PHP / MySQL / jQuery - Developer

    Netherlands - Tests: 6 - Portfolio: 5

    Before working as a web developer I worked in corporate IT in the Netherlands, doing information analysis and Oracle development. After taking some time off to travel I ended up living in Central America (Guatemala). Here I picked up web development by working on personal projects and freelancing. After experimenting with different platforms I ended up with Drupal as my favorite choice. It's power and flexibility never ceases to amaze me and there always seems to be a way to make it do exactly what is needed. Besides Drupal/PHP I also specialize in MySQL, jQuery, D3.js (data visualization) and WordPress.
