01 ยท Overview
Professional Summary

Seasoned IT professional with 19 years of experience across multinational companies, focused on network infrastructure and network operations โ€” with deep expertise in network engineering and network security for datacenter and branch environments spanning LAN/WLAN and WAN/SD-WAN.

My work centers on planning, implementing, and operating resilient networks: from perimeter security and zero-trust enforcement to full-scale office builds and cross-region network merges. I'm most useful in the stretch between "here's the requirement" and "it's live, secure, and monitored."
