About Me

Hi there. I’m a Freelance IT Architect, Consultant, Engineer – living here (Raalte) the east part of the Netherlands, Europe, Earth, The Milky Way.

I use this website to post useful, helpful or interesting things on matters I find in my day to day work. Also I use it as a personal knowledge bank. I perform different roles in various enterprise organisations, most of them have around 2000 up to 15000 employees. The roles I perform include the work as an IT Architect, Cloud/Infrastructure Architect, Citrix Architect (including XenApp/XenDesktop, XenMobile and NetScaler), AirWatch Architect, Security Consultant, Citrix Consultant/Engineer, Microsoft Infrastructure Specialist. I also advise, review, recommend and give seconds opinions on technical / IT related implementations.

Most of my time I spend on Cloud based or Core IT infrastructure software from Microsoft, Citrix and VMWare. Also I keep an overview on storage and networking implementation so “everything fits together seamlessly”

I’ve studied IT Management on the Saxion Universitay of Applied Sciences, in the City of Enschede, The Netherlands. After my study I started working with the IT Department for the local government of the City of Enschede. In the year 2012 it was time for a change, I needed more challenges in my work and found those challenges at KPN Consulting. After that I started working for CGI in the Netherlands (former Logica/CMG), Europe.

In my day to day work I primarily advise, design and implement products of companies like Microsoft, Citrix and VMWare (including AirWatch). Sometimes I do some work on switches, routers, firewalls and storage solutions like a NAS or SAN / Hyper Converged solutions.

I am a Citrix Certified Expert in Virtualization, a Microsoft Certified IT Professional – Enterprise Administrator with additional certification on Exchange, SQL, and SCCM. I am specialized in the architecture and management of Citrix NetScaler, XenMobile, XenServer, XenApp, XenDesktop and Provisioning Server.  I’ve done mayor VMWare Airwatch deployments and I’ve got years of experience with VMWare ESX/vSphere/vCenter server in the larger environments, a 1000+ Virtual Machines.



When I am not working I like to cook and especially I like making Pizza’s & Lasagne…
