Profile

I'm Patrick, a software engineer from Hamburg. Complex problems motivate me, exciting projects drive me. Thanks to my analytical mindset I recognize and solve challenges quickly and in a structured way. Especially in teams my communication skills shine – I work constructively, solution-oriented and with a clear view of cost and benefit.

My sports background taught me discipline and resilience: sticking with it when things get tough and staying calm when the situation allows. New technologies excite me – I continuously develop both professionally and personally.
