My background spans public-sector and commercial IT environments. I have worked with Windows Server, Active Directory, LAN operations, network security, backup and recovery, endpoint support and business applications. In a previous role at the Saransk City Administration, I administered a network of 150+ workstations and three physical servers, and helped modernise the workstation fleet and local network.
Alongside infrastructure work, I develop independent software for Windows and Android — from Windows 11 widgets and market-data tools to fuel-planning and radio applications.
