I am an SAP FI/CO consultant with extensive experience in national and international projects. My focus is on rollouts, transformations, release upgrades, and managing subprojects. In doing so, I take responsibility from functional design through customizing to go-live and hypercare. As an interface between business and IT, I ensure that complex financial processes are analyzed in a structured way, communicated clearly, and implemented pragmatically.

My core expertise lies in the SAP FI/CO modules, where I have successfully carried out implementations, configurations, and process optimizations. With in-depth knowledge of SAP S/4 HANA and SAP ECC, I reliably support companies in implementations, migrations, and release upgrades. Additionally, I have experience in ABAP programming for custom adjustments and developments, allowing me to flexibly meet individual requirements.

I bring extensive experience in leading and coordinating SAP projects, particularly in rollouts and system migrations. In the process, I carefully analyze business processes in accounting, develop practical solutions, and implement them efficiently. My approach combines structured project management with pragmatic process understanding to achieve tangible results for companies.

I have executed SAP projects in numerous countries, taking into account different legal requirements. This international experience has not only given me technical know-how but also intercultural competence, flexibility, and the ability to successfully manage complex projects in various regulatory environments.

If you are looking for an experienced SAP FI/CO expert to support national and international projects with responsibility, technical expertise and a pragmatic process understanding, I look forward to hearing from you.
