Back to original languageAbout Yordan
I support small and medium-sized businesses with the reliable administration, optimization, and security of their IT infrastructure.
With over 7 years of experience in system administration, Windows and Linux servers, VMware, Hyper-V, Active Directory, backup, network administration, and IT support, I help companies operate stable, secure, and well-documented IT environments.
My focus is on practical, solution-oriented IT support: from server administration and user management to troubleshooting, backup control, and system monitoring, to supporting internal teams in 1st, 2nd, and 3rd level support.
I work in a structured, reliable, and remote-oriented manner. Clear communication, clean documentation, and fast, comprehensible solutions are particularly important to me.
IT Infrastructure & System Administration
Administration and support of Windows Servers, Linux systems, Active Directory, DNS, DHCP, Group Policies, and user/rights management.
Virtualization & Server Environments
Support of VMware and Hyper-V environments, analysis of performance problems, maintenance of virtual machines, and support with migrations.
Microsoft 365 & Windows Environments
User management, Exchange/Microsoft 365 support, Windows client and server support, troubleshooting, and support for business environments.
Backup, Monitoring & Security
Review of backup processes, monitoring of system landscapes, error analysis, documentation, and improvement of operational security.
Remote IT Support
Structured 1st, 2nd, and 3rd level support for employees, administrators, and small IT teams.
I particularly enjoy working with small and medium-sized businesses, startups, agencies, law firms, medical practices, remote teams, and companies without their own large IT department.
My goal is to offer companies reliable external IT support that is flexible, professional, and without unnecessary complexity.
