Other Work Experience
• Founder and Executive Board, ITDEVELOP, Aachen, Germany, May January . The
main activities were related to the development of a contemporary communication platform that en
abled interactive locationbased event management. Mobility is becoming evermore important and
present in our society both in business and in private life. People use mobile phones, PDAs and
laptop computers, drive to work and to events, fly to business meetings and on holidays. Although
mobility is increasing and peoples geographical horizons are broadening, information sources did not
keep up.
