About Rene

I am an expert in accounting and fixed assets with over 20 years of professional experience in financial accounting - including over 15 years in fixed assets accounting according to HGB, tax law, and IFRS. Since July 2023, I have been working at Stadtwerke Düsseldorf, where I contribute my expertise in fixed assets accounting, closing preparation, and project work (introduction of SAP S/4 Hana). My focus is on the recording, valuation, and management of fixed assets, the creation of asset registers, deferrals, and support with monthly, quarterly, and annual financial statements. I have comprehensive knowledge of SAP FI-AA and FI-G/L, including customizing and process optimization.
I work in a structured, analytical manner with a high standard of quality - both independently and as part of a team.

I am available for freelance projects up to 10 hours per week and am happy to support with challenging tasks in accounting or SAP.

I am currently supporting an international group in the special mechanical engineering sector with the management of an infrastructure project.
