At HCLTech, I monitor LAN/WAN performance across enterprise network devices and help maintain 99.9% uptime. I troubleshoot BGP, OSPF, and MPLS issues, coordinating with ISPs to restore connectivity within SLAs.
I configure Cisco routers and switches and resolve Layer 2/3 incidents using CLI diagnostics. I also manage incident records and root-cause documentation in ServiceNow.
With Infoblox, I monitor DNS and DHCP infrastructure and manage A, CNAME, and PTR records. In a DNS record audit project, I identified and cleaned stale entries to improve enterprise DNS resolution accuracy.
I developed an ISP outage runbook that reduced average outage resolution time by 20%, and tuned SNMP monitoring thresholds to reduce false-positive alerts by 30%. I hold CCNA, AZ-104, and ITIL V4 certifications and am pursuing CCNP Enterprise.
