About me#

My name is Nic. I am a non-binary human and networking and infrastructure professional living in Berlin. I have worked on IT infrastructure of all sizes, from very small to very large, in various contexts.

I specialise in designing and building IP networks and cloud infrastructure. In 2011 I completed my CCIE (Routing & Switching #28800). My work focusses on making infrastructure visibile, resilient, and sustainable, while considering the often rapid changes in technology and business needs.

From 1999 until 2021 I was working as an employee for various organisations. Since then I have been providing consulting and support services as a freelancer. Below you can find an outline of some of the things I can offer.

Please don’t hesitate if you would like to get in touch with me!
