I worked as a Senior Technical Staff Member at the IBM Research & Development Lab in Boeblingen, Germany till end of 2015. During my active time at IBM I vested the role of software architect in the area of enterprise content managment  (ECM) in the position of manager of the IBM European ECM Competency Center. With my team we prototyped and developed the first IBM content cloud services platform. After leaving IBM in 2015 I joint the the IPVS Application Systems department at the University of Stuttgart. End of end of 2017 Prof. B. Mitschang and I founded a startup , the Content Management Consulting Services GmbH, providing expert consulting on ECM systems architecture design to IBM ECM customers.

My current research is in enterprise information management (EIM), with a focus on migrating legacy enterprise content management (ECM) systems design and their information lifecycle and governance workloads on to modern cloud platforms. A second goal is to help promote the move off, of non-European cloud platforms onto a democratized European data cloud marketplace, aiming at a european digital sovereignty such as envisioned by the GAIA-X initiative. www.data-infrastructure.eu
