At Betera, I provide first- and second-line technical support for employees and resolve workstation, software, and network issues. I also administer 3CX IP telephony and prepare hardware and accounts for new employees.
Previously, as Lead System Administrator at Vitebsk Municipal Housing and Utilities Enterprise, I supported corporate infrastructure with 200+ devices, including Windows Server, Active Directory, and network equipment. I also handled backup and disaster recovery operations and developed information security policies and internal regulations.
