Description

IT expert with over 18 years of experience – currently working as a Linux and IT Administrator

I have been working in IT for over 18 years, with broad knowledge in IT support, system administration, network technology, and hardware/software services.

I am currently working as a Linux and IT Administrator at the German Aerospace Center (DLR). There, I manage Linux clients and servers, perform migrations (e.g., Debian Bullseye), manage NAS servers with backup solutions, and handle complex error analyses – also in Windows environments.

Additionally, I have experience in user support (1st–3rd Level), virtualization, script automation, and system maintenance of small IT environments.

I am looking for exciting side projects or mini-jobs in Linux administration, IT support, or network infrastructure – preferably remote or in the Cologne area.

I work reliably, solution-oriented, and with great technical diligence.
