At Sinowei Private Limited, I resolved Microsoft 365 licensing and access issues, supported Microsoft Entra ID accounts, and troubleshot Outlook and Exchange Online problems.
I also supported users with hardware, printers, Microsoft Teams, SharePoint Online, and meeting-room equipment. I documented recurring issues and troubleshooting procedures to support consistent future resolutions.
At Tata Consultancy Services, I handled L1/L2 incidents, administered Active Directory and Entra ID, and supported Windows Server services including DNS and DHCP. I resolved 200+ customer incidents and prepared computers for employee use.
