As an independent Microsoft 365 expert, I support organizations as an architect, project manager, and administrator to optimize, manage, and secure their Microsoft 365 environments.

My focus lies on designing secure Microsoft 365 tenants with Defender components, implementing Entra ID for identity and access management, and developing Mobile Device Management (MDM) solutions with Intune.

In addition to general Microsoft 365 administration, which includes managing Teams and SharePoint Online, I offer expertise in creating security strategies to protect company data, leading migration projects, and providing training to sustainably strengthen IT security.

As a Microsoft 365 Security expert, I specialize in hands-on workshops, consulting, and architectural support across the Defender suite. My work involves in-depth security assessments and tenant hardening, with tailored strategies to optimize security configurations for businesses.
