About me
I am a full-stack developer and DevOps engineer based in Nuremberg. I work as a freelancer and, part-time, as an open-source specialist at FAU Erlangen-Nürnberg. Before that, at a housing company with around 400 employees, I modernised legacy systems, built integrations between ERP systems and web portals, and introduced GitLab as the central DevOps platform.
My background is in interface design (B.A., FH Potsdam) – so I always think about software from the perspective of the people who use it every day. As a freelancer, I help companies digitise their processes and stay in control of their own infrastructure.
