About ZOO

ZOO Ronnie Stevens

Freelance webdeveloper, Plone expert, and Python developer also working with Django and Wagtail. While focusing on usability, the user-experience is leading in the projects I run.


I am a Plone-specialist, working with Plone more than 10 years. I have build dozens websites with Plone, from small to midsized, and cooperated on major Plone-sites. I have a lot expertise in running, maintaining and supporting existing Plone websites.

Powerful and extremely user-friendly.

Plone has a track-record as a very secure, powerful and user-friendly platform to develop websites and intranets, both for small companies as major organisations. There are dozens of governmental and non-profit organisations that are using Plone.


I work together with my clients to come to an optimal solution. Professional, transparent and informal is what best describes my way of working and cooperating.

Responsive design

A website in 2016 needs to be responsive. I work with Bootstrap, JQuery, Less and Sass to make sure the user-experience is optimized on every device.


Major projects often lack good communication. The gap between technical developers and communication-departments often lead to failures that easily can be avoided. I am able to talk to both developers and communication officers, creating a mutual understanding of the business needs and translating these to solutions that can technically be realised.
