At IT-HAUS GmbH, I managed and strategically developed mid-market and enterprise accounts across IT, workplace, service, and lifecycle solutions. I contributed to RFP/RFI and proposal processes involving volumes up to €6 million, translating technical approaches into business value, ROI/TCO arguments, and decision logic.
I led commercial negotiations on pricing, service models, contract structures, and procurement models. My practical knowledge includes Microsoft 365, Intune, Windows Autopilot, Copilot, and ChatGPT/OpenAI-based workflows.
At Liftstar GmbH, I drove strategic business development, identified growth opportunities, and developed key-account partnerships. Earlier, I supported customer relationships, new-business acquisition, and operational processes at ardax GmbH, and handled customer service and sales across commercial projects.
