Hi, I’m Guido Jansen and I am a Cognitive Psychologist, Data Driven Customer Experience Engineer and a Digital Native. I love testing hypotheses about human behavior in online environments and building communities.


I was born in 1982 in Zwolle, in the Netherlands. Until 1989 I lived in Hattem. After that I moved to Tiel. After a pit stop of three years in Amersfoort and five in Utrecht I currently live in Breukelen (yes, Brooklyn). Until 8 years ago I spent most of my time swimming and I won several Dutch championships doing so. You’ll find out about this in more detail under the tag “swimming“.


I studied “Applied Cognitive Psychology” at the University of Utrecht. When I was studying there, I was on the Board of the Student Group of Social Sciences (SGS) from ’06 to ’07 as a coordinator of Public Relations. For more info about my study/CV you can take a look at my LinkedIn profile.

Online Communities and Events

I’m quite busy in the Dutch “Open Source” community. My main involvement lies with web-based applications and the communities involved with it. I founded one of the largest local Joomla! communities worldwide. Additionally, I was a Dutch translation coordinator for Joomla! for quite some time. I also organized the two-day event Joomladays in 2009.

After many years of Joomla! I switched focus to e-commerce and one system in particular: Magento. I am the Dutch Community Manager for Magento. I’m also part of the Community Advisory Board and I organize the yearly Meet Magento event (4th time in 2012). I previously worked at Magento Gold partner ISM eCompany as an eBusiness consultant and as a Senior Conversion Consultant at Online Dialogue. In 2014 is switched to working at the “Client side”, starting out as a Conversion Manager for Comparison International at Sanoma and now working as Chief Psychology Officer at Euroflorist Europe.

Professional Experience

I worked as a freelancer during my studies and have since been employed at two technology companies. My business cards have always said “e-Business Consultant” on them. Since no-one really has a clear idea of what an e-business consultant really does, this allowed me to do all kinds of cool stuff within those companies. All of my tasks were focussed on e-commerce projects, mainly using the Magento platform and also included:

  • Working in mixed teams with clients, front-end and back-end-developers and designers, both locally and internationally.
  • Pre-sales consulting (why and how companies should use Magento).
  • Writing functional design specifications/ responses to RFPs / project proposals.
  • Project management (following the SCRUM method, with both Dutch and Ukrainian developers).
  • After-sales consulting (how companies could improve their current Web-shop).
  • Setting up usability and A/B testing procedures.
  • Creating and developing new business ideas.
  • Blogging and speaking about Magento and (Online) Psychology at events.

This gave me the opportunity to explore almost every aspect of the e-commerce business from the side of an implementation company.
