Back to original languageAbout Michael Donald
I am a qualified and experienced IT system administrator. In the industrial environment, I support companies in modernizing, securing, and efficiently automating their IT infrastructure. My focus is on Microsoft ecosystems, hybrid environments, and intelligent process optimization.
Through my daily practice in managing complex corporate IT, I bring in-depth expertise in administering Microsoft infrastructures as well as Linux server landscapes. I specialize in eliminating time-consuming routine tasks in your IT department and minimizing security risks.
My core competencies for your project:
- Identity & Access Management: Structuring, cleaning up, and securing local Active Directory and seamless integration with Microsoft Entra ID (Azure AD).
- IT Automation: Developing customized PowerShell scripts (e.g., for automated user onboarding/offboarding and permission assignments).
- Endpoint & System Management: Reliable management via Intune and SCCM, as well as administration of SQL databases.
- Virtualization & Networks: Support and migration of server landscapes based on VMware and Hyper-V.
I support your projects flexibly, goal-orientedly, and 100% reliably on a remote basis (on-site inspection or troubleshooting upon request).
Whether as project-based support for SMEs or as a specialized subcontractor for IT service providers, I deliver solutions that work and provide real added value.
Let me make your IT processes more efficient. I look forward to your project inquiry!
