About Engelbert

In my role, it is always of particular importance to contribute my methodical skills within the team at the client's site in a profitable way. The following two points have helped me achieve high customer satisfaction. On the one hand, my core competence of analytical-critical thinking, and on the other hand, the necessity to develop the optimal solution within a team. In my work, it is important to me to promote a structurally organized work atmosphere, so that there is clarity and transparency for everyone involved in the process.

I prefer a goal-oriented, efficient way of working. I enjoy working independently and self-organized. Professional communication is important to me, especially in complex customer environments.
