Freelancer profile translated to English.

Description

With over 30 years of experience as a System Administrator, I support companies in the administration, optimization, and troubleshooting of their IT infrastructure. My focus is on Windows Server, Microsoft 365, Active Directory, Exchange, as well as Apple/macOS. Furthermore, I have extensive experience with virtualization (VMware, Proxmox), backup solutions, networks, firewalls, and 3CX. I work in a structured, pragmatic, and solution-oriented manner and preferably support companies remotely with clearly defined technical tasks – reliably, understandably, and with the goal of creating sustainable solutions.
