IT-Administration

Seamless integration of Windows Server, Active Directory and Microsoft 365

Modern IT environments increasingly require a hybrid IT infrastructure: local control over sensitive business data combined with the flexibility of cloud-based services. I support organizations in securely and reliably integrating Windows Server, Active Directory and Microsoft 365 (M365) into a coherent environment.

The focus is on reliable administration of Windows Server environments and the structured design and ongoing maintenance of Active Directory services. The goal is a consistent, maintainable and secure foundation for hybrid working environments.

Whether it involves the migration of on-premises Exchange servers to Microsoft 365, the implementation of hybrid identity solutions, or the optimization of existing directory services, I ensure a smooth data flow, clear responsibilities and a high level of security. Particular attention is paid to:

Centralized user and identity management
Consistent identities across on-premises Active Directory structures and Microsoft 365 services.

Data security & compliance
GDPR-compliant configuration of cloud tenants, access policies and on-premises resources.

Resilience & backup strategies
Robust backup and recovery concepts for hybrid Windows Server and M365 scenarios.

IT support on equal footing in Berlin: discreet, open, and reliable

Professional IT support and IT administration is about far more than servers, updates, and troubleshooting — it’s about a long-term partnership built on mutual respect. As an owner-operated business, I place the highest value on a non-judgmental, respectful collaboration. It is important to me to create an environment in which my clients’ individual circumstances are respected and technical questions can be addressed in a protected space.

With more than 30 years of experience in IT administration and software development — including a deep developer background (C/C++) — I bring not only operational routine, but also a profound technical understanding of complex infrastructures and clean, maintainable solutions.

Small businesses and self-employed professionals in Berlin value my work especially for absolute discretion and personal availability. With me, you are not an anonymous ticket number: I know your infrastructure and keep your IT stable, secure, and maintainable — so it supports your core business instead of slowing it down.

Whether Bayerisches Viertel, City West around Ku’damm, or Kreuzberg: I’m your dedicated point of contact for on-site IT support and IT administration in Berlin, combining technical excellence with a genuine focus on people.
