I am a Senior Network & Infrastructure Engineer based in Kyiv, Ukraine, with over a decade of hands-on experience building and securing enterprise-grade IT environments. My career has included senior roles in UAE-based organisations before returning to Ukraine.

My expertise spans network architecture (LAN/WAN/VPN), data center operations, cybersecurity monitoring, SIEM implementation, and incident response. I specialise in building resilient infrastructure that performs under real-world pressure.

Proven track record of designing multi-site networks, managing Cisco environments at scale, and integrating cloud technologies with on-premise infrastructure. Currently open to senior infrastructure and security roles.
