I work solution-oriented, structured, and with a clear focus on stable, documented systems. My goal is an IT that functions reliably in everyday use, is well-maintained, and is professionally set up even in the background – without unnecessary complexity, but with high traceability.

I am available nationwide – remotely or on-site – and look forward to your project.
