Narinder Sharma | IT Support & Service Desk Analyst

Information Technology Professional focused on IT Support, Service Desk, Technical Support, endpoint troubleshooting, Microsoft 365 / Entra ID administration, Linux fundamentals, and technical documentation.

I build hands-on portfolio projects that document how support environments are configured, administered, validated, and maintained. My current work focuses on Microsoft 365 / Entra ID administration, role-based access, ITSM ticket workflows, structured troubleshooting runbooks, Linux command-line practice, and clear technical handoff documentation.

  • Windows Server & Hybrid Identity: Windows Server AD DS and DNS, Active Directory user and OU preparation, IDFix directory cleanup, Microsoft Entra Connect Sync, Microsoft Entra Cloud Sync, Password Hash Synchronization, synchronization scoping, synchronized identity verification, and Connect Health troubleshooting.
  • Service Desk & ITSM Operations: Jira Service Management configuration, request intake, ticket triage, JQL-based queues, SLA tracking, escalation paths, and support workflow documentation.
