After studying communications engineering at the University of Applied Sciences in Munich, I joined Cisco Systems as a network specialist in 1995 and worked there for seven years as a systems engineer.

My knowledge includes IP switching / routing for large enterprises, LAN and WAN switching, VoIP and VPN technologies. I was one of the pioneers in the introduction of VoIP and provided technical support for many installations. After that I specialised in WAN switching infrastructures. My biggest project, which I managed as a team leader, was the design and rollout of the MPLS backbone for AT&T in Europe. I was based in London for three years.

In 2004, I founded the engineering company CUI with my partner, based in Munich. Specialising in VoIP infrastructures, we have realised over 80 projects in the Munich area and internationally, including contracts for the ESO Observatory, the European Patent Office, the Bavarian Police, which also required a security audit, the Agrana company and many municipal infrastructures and district offices.

A recent project is that of the Münchener Hypothekenbank, where we networked all branches nationwide via VPN technologies using multimedia.

In addition, we have focused the engineering office on the new technologies "Flexible Smart Grid" and realised the first PoCs for intelligent charging solutions for Stadtwerke München and the company Sonnen.

Currently, after Corona, I have been permanently employed at The Mobility House since June 2022 and, as a software engineer, I lead two development teams that deal with the connection of charging stations to an overarching charging infrastructure.

DVI, my first team, deals with a decentralised component that realises the load distribution of many charging points in car parks, while my second team, CCSMS, develops an AWS-based cloud solution for the connection of EVs of a car manufacturer.

I have detailed knowledge of communication solutions from Cisco Systems, Avaya, Mitel, Alcatel and Siemens and instant messaging/conferencing applications such as Slack/Huddle, Zoom or Teams.
