As an interim manager, I support companies in demanding phases – from operational scaling and financial restructuring to repositioning in crisis situations. With more than ten years of leadership experience – including as managing director, production manager, and interim manager – I support mid-sized companies and large corporations in implementing major changes. I bring technical know-how as a mechanical engineer, a solid understanding of controlling and management, and intercultural experience. My focus is on structured analysis, clear progress, and consistent execution – hands-on, assertive, and always focused on what matters most.
