Summary

I have more than 15 years of experience in demanding, large, and complex IT environments. Through many tasks and projects, I have built extensive knowledge in various areas. In enterprise environments with high security requirements, the BSI IT baseline protection (ISO 27001) forms the basis of IT security and was part of my daily work. My areas of responsibility include IT administration and IT coordination/control, software distribution via MECM, as well as user and rights management. One focus is mediating between the business and IT departments, third-party or subsystems, the IT infrastructure, different locations, external service providers, and suppliers. MECM software distribution, developing solutions in collaboration with product owners and packagers for deployment and troubleshooting of MECM software packages are part of my responsibilities. Administration of permissions based on a role concept as well as user and account management in complex and diverse environments. Tasks in helpdesk and support – troubleshooting, request, incident, and change management/processing in test, reference, and production environments, plus defect management and processing in multi-forest environments. My skills are rounded off by experience in customer support, strong communication skills, and working according to ITIL and processes. Many years of work as a certified Microsoft and CompTIA trainer.
