At HAN Gebäudereinigung GmbH, I built and continuously developed sales structures, won new customers through cold calling, and managed the full sales process from initial outreach to site visits, proposals, contract negotiations, and closing.

I create efficient, scalable workflows and introduced a structured sales pipeline using Trello and Excel. My approach is to understand customers' challenges and develop sustainable solutions that deliver real value while building long-term relationships.

Previously, I managed overnight hotel operations at Bellcaptain GmbH and helped run a family business, coordinating daily operations, staffing, and employees.
