At tk accelis Digital Innovations GmbH, I continue as Program Lead for the Organizational Cloud Transformation program, “Enterprise IT Services and Infrastructure.” Previously, at thyssenkrupp Management Consulting, I led work across cloud transformation, data center migration, and the cloud-managed workplace offering.

My work has also included SaaS implementation for supply chain ESG, HR WORKDAY deployment and cutover management, and IT carve-out and post-merger management. Across roles with Deutsche Bahn Fernverkehr, Telefonica, Vorwerk, AUDI AG, Vodafone, Swisscom, and others, I’ve managed IT programs and product transitions, including CRM rollouts and billing platform migrations.
