At TataConsultancyServicesPvtLimited, I provide Day-2 network operations and L2/L3 support for IKEA’s network across 520+ retail sites. I troubleshoot Cisco and Aruba infrastructure, manage incidents and changes in ServiceNow, and carry out software upgrades and network migrations.
I reduced false access point alerts by removing decommissioned and inactive devices from monitoring, and resolved CRC errors across core links and switch uplinks through cable and SFP replacement. I also maintain network documentation and configurations while coordinating with Local IT, ISP vendors and TAC teams.
