IT Specialist from Finland with 20+ years of experience in Windows Server, Active Directory, Group Policy, Microsoft 365, Microsoft Entra ID, Microsoft Intune, Exchange Online, PowerShell, Linux and infrastructure operations.
I build practical tools for IT auditing, endpoint management, security reporting, automation and system health checks. My focus is on clear reporting, safe automation and public-safe scripts that can be shared without customer-specific data.

The remaining warnings are historical workflow failure findings in cpanel-backup-dr-toolkit and dos-healthcheck, not active repository issues.
My public repositories are built with a consistent structure:
- Public-safe code with no customer-specific data

- README, SECURITY.md, VERSION.txt and checksums
- GitHub Actions for script analysis, tests, secret scanning and public-safety checks
