At HCLTech, I support critical data-center and corporate network infrastructure for Microsoft, including connectivity across CorpNet, hybrid lab services, and Azure lab infrastructure.
I troubleshoot routing, switching, high-availability links, and hardware across Cisco ASR 9000, Nexus, Catalyst 9000, and Arista DCS platforms. I also carry out approved IOS and firmware upgrades and hardware refreshes, from pre-checks through validation.
I deploy and troubleshoot Aruba wireless infrastructure and maintain out-of-band access through Opengear and Lighthouse. I manage incidents in IcM and ServiceNow, coordinate OEM TAC and RMA activities, and support restoration during escalated outages.
Previously, I supported ICICI Bank branches and data centers at Diversified Network InfraPvt. Ltd., including WAN troubleshooting, SolarWinds monitoring, and migrations to Cisco Viptela and Versa SD-WAN. Earlier, at Techwave Infotech India Pvt. Ltd., I handled first-line fiber connectivity troubleshooting and incident tickets for NBN Australia.
