About

Professional summary

I am an IT Infrastructure Engineer with more than a decade of experience supporting enterprise Linux and Windows environments. My background includes technical support, network operations, server administration, virtualization, monitoring, and infrastructure troubleshooting.

I investigate business-critical incidents involving server availability, network connectivity, storage, application performance, and service configurations. I use system logs, monitoring alerts, and structured troubleshooting practices to restore services and improve operational reliability.

I have strong hands-on knowledge of TCP/IP networking, DNS, DHCP, VLANs, L2/L3 switching, routing, firewalls, Active Directory, and Group Policy. I am experienced in supporting enterprise network services, telecommunications infrastructure, and data center operations.

My Linux operations experience includes shell administration, service management, log analysis, filesystem administration, and troubleshooting across Oracle Linux and Ubuntu/Debian environments. I also support Windows Server infrastructure and automation using PowerShell and shell-based tools.

I work with virtualization and container platforms including Proxmox, XenServer, oVirt, Docker, and Docker Compose. I have used Zabbix, Grafana, and Graylog for infrastructure monitoring, alert investigation, and operational analysis.

I also build independent technology projects focused on automation, deployment reliability, AI, Web3, and blockchain. I value clear technical documentation, proactive monitoring, secure infrastructure operations, and practical solutions to complex support issues.
