Summary

6 years in technical asset management
5 years as an architect for investor projects
Independent working style
Result-oriented communication and negotiation
Proactive teamwork

I have extensive experience in real estate – from planning and construction to operation – and have worked successfully with investors and project stakeholders for many years. I value working independently with a clear focus on goals and always strive to find the best solution within the given time and cost limits.

Constructive collaboration is very important to me: I have a good sense of how tasks can be best performed by different team members and can find viable, shared solutions even in challenging situations. I am skilled at motivating participants and getting them on board with common goals.

I like to work in a structured way, appreciate clear responsibilities, and make balanced decisions. At the same time, I support those around me in making well-founded decisions themselves – whether that’s through professional input or a shift in perspective.

I hold a valid driver's license and have full willingness to travel.
