I began my career with Hays in May 2014 as an Account Manager at our Essen offices, where I worked in IT Contracting for various medium-sized companies.

Starting October 2014, I took over responsibility for a DAX 30 company and was its Client Manager until September 2017.

Since moving to a new internal position in October 2017, I have been responsible for developing our SoW (Statement of Work) business as a Business Development Manager.

In this capacity I am responsible for our western and southern regions with locations in Stuttgart, Ulm, Nuremberg, Munich, Frankfurt, Mannheim, Cologne, Düsseldorf and Essen.

I joined Hays in spring 2012 and worked in Sales for over 6 years. As Business Development Manager, I have been responsible for expanding our statements of work business in Northern Germany since 2018.

After graduating with a degree in Business Administration, I began my career as Regional Manager at ALDI Süd.
Since 1999 I have been employed by Hays and have gained operational and management experience in almost all specialisms and contract models.
For the majority of this time I have worked in Germany and have over 15 years experience in IT and the process business – a good combination of skills for taking on the responsibility for IT Services & Solutions at Hays Germany.
