Narinder Sharma | IT Support & Administration Portfolio

This GitHub profile collects my technical portfolio work in Microsoft 365, Microsoft Entra ID, Microsoft Intune, service desk operations, Windows troubleshooting and Linux. I use the repositories to document what I configured, the issues I investigated and how I checked the results.

The Microsoft administration work was carried out in non-production lab environments. The Jira Service Management lab uses simulated support requests, while the knowledge base and Linux labs contain troubleshooting runbooks and command-line notes.
