Über mich

Geboren und aufgewachsen bin ich in Paderborn, einer Stadt in Ostwestfalen. Mit ungefähr 10 Jahren habe ich meinen ersten Computer bekommen und war sofort von der Technologie begeistert. Daher war die Ausbildung als Fachinformatiker für Systemintegration an der Universität Paderborn eine logische Konsequenz. Anschließend zog es mich in die - auch aus technologischer Sicht – sehr spannende Stadt Berlin, wo ich seitdem als Systemadministrator tätig bin.

In meiner Freizeit mache ich viel Sport. Meinen ersten Marathon habe ich schon geschafft. Als Kontrastprogramm dazu verbringe ich auch immer noch gerne viel Zeit vor dem Computer und beschäftige mich mit neuen Dingen.
