Martin Rublík

Identity and Microsoft 365 architect, engineer and occasional PowerShell enthusiast.

I work mostly with Microsoft Entra ID, hybrid identity, identity and access management, Microsoft 365, Active Directory, PKI and security.

I like problems that sit somewhere between architecture and troubleshooting: identity synchronization, authentication and federation, tenant migrations, application integrations, Conditional Access, permissions, certificates, strange Graph behavior and the occasional issue that only appears in production.

My professional background includes:

  • designing identity synchronization and authentication infrastructures for environments with 50,000+ users,
  • participating in large Microsoft 365 tenant-to-tenant migrations, with a focus on identity, access and migration dependencies,
  • implementing PKI environments with 20,000+ subscribers,
  • Microsoft Information Protection / Purview, DLP and cloud security,
  • Active Directory, AD FS, Entra Connect and Microsoft Identity Manager,
  • :blue_heart: PowerShell :blue_heart:, Microsoft Graph and automation.

I still prefer understanding how things actually work over treating technology as a black box. Most posts here originate from something I had to investigate, test, fix or explain at work.
