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.


Professional Focus

  • Microsoft 365 & Identity Administration: Microsoft 365 admin center, Microsoft Entra ID, tenant/domain readiness, user provisioning, external contacts, B2B guest users, Microsoft 365 groups, licensing review, service health, Microsoft 365 Backup readiness, Microsoft Graph PowerShell, CSV-based bulk provisioning, role-based access, administrative units, scoped delegation, Purview role groups, and PIM-style eligible access workflows.
  • Service Desk & ITSM Operations: Jira Service Management configuration, request intake, ticket triage, JQL-based queues, SLA tracking, escalation paths, and support workflow documentation.
  • Endpoint & User Support: Windows 10/11 troubleshooting, account access issues, printer/peripheral support, mobile device support, endpoint maintenance, and user-facing technical communication.
  • Linux, Networking & Cloud Fundamentals: Ubuntu/Linux command line, Bash basics, SSH, permissions, file handling, TCP/IP, DNS/DHCP, Wi-Fi/Ethernet troubleshooting, VPN support concepts, and AWS Cloud Practitioner-level cloud fundamentals.
  • Technical Documentation: Incident reports, troubleshooting runbooks, root-cause analysis notes, Markdown documentation, and Git/GitHub portfolio maintenance.
