What I'm looking for

I’m looking for a working student position where I can contribute my SAP experience and deepen my knowledge of SAP transformation, data governance, and AI.

At Putzmeister Engineering GmbH, I led material master creation and governance for the SAP ECC-to-S/4HANA landscape, partnering with SANY to cleanse more than 300,000 material and equipment records. I also used SQL Server for deduplication and validation, reducing analysis time from hours to minutes.

I created the end-user training package for the Siemens Teamcenter AWC transition and delivered it as official internal training. Now studying Digital Technologies at TU Clausthal, I’m looking for a working student position where I can contribute my SAP experience and deepen my knowledge of SAP transformation, data governance, and AI.
