Freelancer profile translated to English.

Description

I am an ABAP developer with experience in implementing and further developing business processes in SAP R/3 and S/4HANA. My focus is on both procedural ABAP development and object-oriented programming (ABAP OO). I work with relational databases and SAP HANA, use the SAP Enhancement Framework (BAdIs), and develop enhancements and customer-specific solutions in various modules, including RE/FX and MM.

In addition, I implement interfaces (IDoc, RFC, OData, Cloud APIs), create reports and workflow enhancements, process tickets in the SAP Solution Manager, and perform tests and quality assurance. With my experience in rollout, migration, and system conversion projects, I reliably support companies in the technical implementation, adaptation, and optimization of their SAP landscape.
