Summary

I have built a solid expertise in SAP security and authorization over many years, supporting companies in optimizing access, managing roles, and ensuring compliance across both SAP R/3 and S/4 HANA landscapes with FIORI-Apps. I focus on practical, hands-on solutions that meet stringent requirements while streamlining processes using tools like XAMS, JIRA, and ServiceNow.

My work has consistently helped businesses improve control environments and reduce risks through clear, tested security frameworks. I bring a deep understanding of technical systems, thorough SoD checks, and a collaborative approach that makes complex transformations manageable and secure. My focus during the last time is on SAP license optimization.
