What I'm looking for

I’m seeking an L1/L2 IT Support role in Kaunas.

At Vodafone Retail, I provide L1/L2 support for employees and retail locations, troubleshooting incidents remotely and on site. I work with Windows workstations, Active Directory, and Microsoft Office and Outlook.

I support VPN and VDI access, endpoint deployments through Microsoft SCCM, and business applications including SAP Logon and Dynamics NAV. I also diagnose issues with printers, POS terminals, and payment devices, coordinating escalations through service-desk processes and SLAs.

Through independent IT support projects in Kyiv, I handled PC and laptop troubleshooting, Windows recovery, device setup, and network and peripheral configuration. I’m seeking an L1/L2 IT Support role in Kaunas.
