Summary

With more than 30 years of professional experience in IT, I have solid expertise in networking, virtualization, and cloud technologies. Since my training as a business informatics specialist, I have been deeply involved in the design and implementation of network infrastructures as well as the development of server-client architectures.

Cloud technologies are among my core competencies, especially in the context of migration, building, and optimizing modern IT infrastructures. My goal is always to develop the most efficient and sustainable solution for each individual requirement. I am also skilled in working with Windows Server environments and platforms like Proxmox to deliver forward-looking and high-performance solutions.

Another focus of my work is IT security. Among other things, I have successfully prepared, supported, and completed audits according to ISO standards and BSI basic protection guidelines. Creating detailed risk analyses and developing well-founded security concepts are among my strengths.

In addition, I have extensive experience in implementing CRM and ERP systems, leading teams, and setting up decision-making processes. I work both in line with ITIL standards and within agile project structures, placing great emphasis on a goal-oriented and solution-focused approach.
