About
After school in Thuringia, my path into computer science led me to Berlin. When I was only studying, I missed the practical work; when I was working on projects, I missed the academic exchange. So first a dual study programme, and later a part-time master's.
During my master's in Data Science I realised that my real interest lies in data engineering, the practical infrastructure layer everything else is built on.
