I'm currently keeping Windows Server, Microsoft 365, MSSQL, networks, ERP web interfaces, and endpoint deployments running at aim – Akademie für Bildung und Management gGmbH.
Previously at OLI Systems GmbH, I administered cloud and IT infrastructure, supported internal users through 1st–3rd level support, managed Sophos security, backups, Salesforce, Azure, Entra ID, Intune, and Exchange.
I also provide freelance IT support and system administration, helping private and business clients implement, maintain, troubleshoot, and improve Windows systems, networks, security, and complex IT infrastructure.
