Portrait of Jeroen Tielen

Solution Architect, Distinguished Consultant and Nutanix Certified Instructor
Nutanix, Citrix and end user computing. Based in the Netherlands, working worldwide. In IT since 1996.

Profile

IT specialist with thirty years of experience in consultancy, architecture, troubleshooting, training and technical account management. I started with Citrix WinFrame in 1996 and have been working with virtual desktops and applications ever since. Since 2017 my focus is Nutanix: I design, build and migrate environments for customers, and I teach the official Nutanix courses as the only Nutanix Certified Instructor in the Benelux.

I know my trade and I do not rush things: what I deliver is built to last. I work well in a team and I am just as comfortable making decisions on my own. Technically I am at home in Citrix, Nutanix, Microsoft, VMware and Ivanti environments, on the client and on the server side, which makes me a good fit for projects as well as third-line support.

You do not get it for passing exams. Nutanix selects the champions itself, about a hundred people worldwide, and you have to earn it again every year.
