Summary

I am a SAP Basis Administrator/Consultant with many years of experience in administering, migrating, and optimizing SAP systems, including SAP ERP, SAP BW, SAP HR, and SAP HANA. I have built and maintained reliable and stable system landscapes in various industries – from airport technology to healthcare and finance.

My focus is on system installation, maintenance, and troubleshooting. I have continuously expanded my skills in S/4HANA migrations, cloud solutions, and various security concepts.
