Summary

6 years of Technical Asset Management
5 years as an Architect for investor projects
Independent way of working
Results-oriented communication and negotiation
Proactive team player

I have extensive experience in real estate - from planning and construction to operation - and have been working successfully with investors and project stakeholders for many years. I value an independent, goal-oriented work style and always strive for the best possible solution within the given time and cost limits.

Constructive collaboration is particularly important to me: I have a good sense of how tasks can be best implemented for different team members and find viable, joint solutions even in challenging situations. I succeed in motivating stakeholders and aligning them with common goals.

I like to work in a structured way, appreciate clear responsibilities, and make decisions with good judgment. At the same time, I support my colleagues in making well-informed decisions themselves - whether through professional input or by offering a change of perspective.

A driving license and full willingness to travel complete my profile.
