Freelancer profile translated to English.
Back to original languageAbout Arash
I am Arash Mahmoudi, a Business Informatics graduate (B.Sc.) and a freelance Financial and Production Controller based in Cologne. My core expertise lies in product costing based on machine hourly rates – from cost center accounting and calculating manufacturing costs to preliminary and final costing. This combination of methodical know-how and SAP expertise (S/4HANA, ECC 6.0, FI/CO) makes me a reliable contact for manufacturing companies. In my previous projects, I have, among other things:
Been responsible for product costing for chemical products according to IFRS (ARLANXEO)
Implemented a complete controlling system from scratch, including machine hourly rates for 55 machines (Wilhelm Alte GmbH)
Independently taken over plant controlling and budgeting (Solventum, WKW AG)
Implemented KPI systems and contribution margin calculations (Pflitsch GmbH)
I work in a structured manner, communicate clearly with management and production, and am ready for deployment at short notice – even in complex SAP environments.
