As a Hays director, I am responsible for the company's Public Sector Services in Germany.

As a Key Account Manager, Team Leader and Department Manager, I were operationally and strategically responsible for customers in the private and public sectors for over ten years. This included local authority data centres as well as agencies of the German Federal, State and local authorities.

During this time I became thoroughly acquainted with a broad range of cost-effective procurement structures, optimising and developing these further in collaboration with his many customers.

I am on the Advisory Board of the Deutsche Vergabe Netzwerk (DVNW - German Procurement Network).

After completing my degree in Business Studies at the Fontys Hogeschool Venlo, The Netherlands, I began my career with Daimler-Chrysler Sales Organisation Germany (DCVD) in 2001.

At the end of 2003, my career took me to Hays, where until March 2013 I held the positions of Account Manager, Key Account Manager and Team Leader.

In these roles I was responsible for supporting numerous private sector customers in Mannheim, Berlin and Hamburg with their IT and engineering needs. Since April 2013, I have been the head of IT Public Services with regional teams in Hamburg, Hannover, Cologne and Düsseldorf looking after public sector clients in the German Federal States of Schleswig-Holstein, Lower Saxony and North Rhine-Westphalia.

After completing my psychology studies, I joined Hays as a Public Services Account Manager in Munich in 2012. 

Since that time, I have been the contact person for representatives of the various state ministries and offices, municipal institutions, church organisations, foundations, associations and many other public sector organisations in southern Germany regarding IT projects/IT contracting/IT freelancers. 

As a team leader, I work closely together with my colleagues, who specialise in recruiting and procurement law, to seek out the most appropriate IT experts for you. We cover areas such as network/infrastructure, development and IT security/IT forensics, but are also equipped to deal with specialist areas of specific importance to public sector authorities.
