Because we can’t shake hands I don’t have a clue who you are. It could be that we met at The Next Web conference, a scientific conference, WordCamps, WooCommerce Meetups, WordPress Meetups, on the street, or at an in-house workshop. I really don’t know. There is even the possibility that you don’t know me…

So let me briefly introduce myself.

Yep, that’s me showing a rare selfie!
Yep, that’s me showing a rare selfie!

My name is Evert. I am living in Amsterdam with my wife, and son.

I am a neuropsychologist and a developer. Early 2016 I defended my doctoral thesis on ADHD in Older Adults and in 2017 I co-founded Neurofied.


I’m developing website with WordPress since 2004 and webshops with WooCommerce since 2011. In 2008 I founded Fourleafed where I specialised in optimising WordPress & WooCommerce websites. After my PhD I made the bold move to be self-employed and became an official WooExpert for almost three years. In 2017, I co-founded Neurofied with Beirem Ben Barrah and retired Fourleafed.

Bigger plans

After several successful years running Fourleafed by myself I had bigger plans. That’s when Neurofied happened. Together with Beirem Ben Barrah we combined Fourleafed, AdWalk, Shroomie and GGZ Vacatures into Neurofied to keep up with the growth of our clients and the growing number of new clients.


At Neurofied we do several things. Firstly, we apply our knowledge of neuropsychology and marketing to websites and webshops and help them grow and improve. Secondly, we present neuromarketing workshops (in-house and at conferences), we give talks at WordCamps, WooCommerce meetups and WordPress meetups. Finally, we perform eye-tracking studies to improve real-world experiences.
