Back to original languageAbout Andreas
I help small and medium-sized businesses securely migrate their IT to Microsoft 365 and operate it stably.
My focus is on migrations, building modern Azure infrastructures, and hybrid environments (On-Prem ↔ Cloud).
I accompany the entire process:
from analysis through implementation to operation and clean handover.
Typical Projects:
✔️ Migration of existing e-mail systems to Microsoft 365 or Google Workspace
✔️ Microsoft 365 Tenant Setup incl. Security & Compliance
✔️ Azure Infrastructure (VMs, Networking, Storage)
✔️ Hybrid AD / Microsoft Entra ID Integration
✔️ Operation & Optimization of existing hybrid environments
Technology Focus:
Microsoft 365 (Exchange Online, SharePoint, OneDrive, Teams)
Microsoft Entra ID (Azure AD, Conditional Access, MFA)
Azure (IaaS, PaaS, Virtual Desktop, Networking)
Microsoft Intune (MDM/MAM)
Microsoft Defender & Security
Windows Server (Active Directory, DNS, DHCP)
Hybrid Cloud (On-Prem ↔ Azure)
Additionally:
Linux (Operation & Optimization)
Working Method:
I work pragmatically, solution-oriented, and with a focus on stable operation.
No theoretical projects, truly functioning systems in everyday use.
For Customers, This Means:
✔️ structured migration without chaos
✔️ secure and scalable cloud environment
✔️ clear handover and sustainable operation
✔️ minimized downtimes and smooth transition
✔️ clear project structure with transparent communication
✔️ sustainable operation and reliable ongoing support
I can also optionally support with:
- Firewall integration (Fortinet, pfSense, MikroTik)
- Virtualization (VMware, Proxmox, Hyper-V)
- Monitoring & Analysis (CheckMK, Wireshark)
I work in a structured manner, am quickly deployable, and have a clear focus on stable results in ongoing operations.
