Summary
Experienced project manager and leader with over 15 years of professional experience in telecommunications, IT and the energy sector. As Director Sales Steering at ista and Head of Performance Management at Vodafone, I led teams and successfully delivered complex projects. In my role at Peek & Cloppenburg, I was responsible for coordinating marketing materials internationally across all channels (TV, out-of-home, print, POS) – from planning and aligning with design teams to on-time execution. My strengths lie in hands-on management of international campaigns, coordinating cross-functional teams and external partners, and ensuring consistent brand execution across multiple markets. I bring extensive experience in project management for marketing roll-outs.
My work style is structured, solution-oriented, and driven by strong ownership, communication skills, and the ability to meet deadlines and budgets even under pressure.
