Freelance DevOps engineer / PHP developer

If you’re looking for a freelance DevOps engineer or PHP developer, feel free to contact me! I usually do freelance jobs that last about 6 – 20 months. As DevOps engineer I’m an expert in Jenkins, Chef, but also know about Puppet and Ansible. As developer I’m an expert in Zend Framework, but also have a lot of knowledge and experience with Symfony. Aks for my CV to get a complete overview of my skills and expertise, read for a summary further down this page or check my LinkedIn profile.

I love to work with open source tools and software, but also love to share and give back to the community! For example, I created a Chef community cookbook “jenkins-server” that configures a complete Jenkins server and php-template, to be used for continuous integration.
For my own administration I created the Invoice module which I shared as open source and is available on the Drupal website as official module. It’s installed in 550 websites that share if they installed it (so probably a lot more) and is downloaded 20.000+ times!
