About me

IT Systems Specialist with over 13 years of experience in maintaining IT environments, systems administration, and supporting business operations and end users.

I began my career in technical support and end-user assistance, gradually developing my expertise in systems administration, virtualization, and IT service management. This path has given me a broad understanding of IT infrastructure, ranging from end-user requirements to system-level services that support business operations.

I specialize in Microsoft and Linux environments, including Windows Server administration, Microsoft 365, Active Directory, and virtualization technologies such as Hyper-V, VMware, and Proxmox.

My experience includes infrastructure monitoring (Zabbix), backup and recovery management (Veeam), production environment maintenance, troubleshooting system-related issues, and ensuring the continuity and reliability of IT services.

I apply practical networking knowledge during deployments, migrations, and infrastructure troubleshooting. While networking is not my primary specialization, I consider it an essential component of reliable and efficient IT systems and services.

Over the years, I have gained experience in both corporate environments and business-oriented IT services supporting organizations across various industries. This has allowed me to develop not only technical expertise but also an understanding of business needs and the importance of stable, reliable IT systems.

I am particularly interested in IT automation, modern infrastructure solutions, and tools that improve the efficiency of daily systems administration tasks.
