Dimitriy Leontev | Systems and Network Administrator

I'm a Network Administrator in public-sector IT. I started in frontline support, including a role as an IT Support Specialist. Today I troubleshoot across networks, servers, cloud services, and endpoints, and use PowerShell to automate repeatable work.

My work spans Windows Server and Ubuntu Linux, Cisco switching and SonicWall firewalls, Azure, and Microsoft 365 administration. That includes Exchange Online, Teams, Microsoft Entra ID, Microsoft Defender, and Microsoft Purview. Technical skills and experience

Education and interests

I earned my computer science degree at the University of Washington Bothell, where I'm now pursuing a Master of Science in Computer Science & Software Engineering. I'm also working toward additional professional certifications.

My personal projects explore release automation, verification, and recovery planning.
