About me

what some of my teammates say

The cooperation with you was always great. Thank you very much for that.
I always found the cooperation with you very constructive and successful.
I always thought, it was cool to work with you. Even if we didn't always agree, we always had super constructive discussions and came to a great result.
We have "lived through" many topics together over the years. It was not always easy, but I have always appreciated it very much, that one could "discuss hotly" with you and afterwards also work calmly together again!
I would like to thank you very much for all the work we have done and especially for all that you have taught me.
I thank you for your collaboration. You contributed to me documenting business logic, at one point or another. That also helped me sort out my thoughts and I still watch the docs today. Thank you so much. I have learned from you.
