Network Engineer at SAMSUNG SDS troubleshooting enterprise, manufacturing, and data-center networks.

At SAMSUNG SDS, I operate and troubleshoot enterprise, manufacturing, and data-center networks built on Cisco Catalyst and Nexus switching, routers, Palo Alto firewalls, F5 load balancers, and wireless infrastructure.

I support hardware lifecycle maintenance and platform upgrades, including Cisco IOS/NX-OS upgrades, pre-change validation, maintenance coordination, and documented rollback plans.

When Layer 1–3 incidents arise, I investigate connectivity and routing issues, restore services, and validate network resilience. I also use SolarWinds, SNMP, syslog, and packet captures to investigate alarms and document root causes and corrective actions.

Previously, at Aviat Networks, I configured, maintained, and troubleshot LAN/WAN infrastructure, and at Benchmark I supported Cisco routing and switching and Meraki SD-WAN. I hold Cisco CCNP and CCNA certifications.
