At NLTS, I architected and deployed a multi-site Cisco ACI fabric across two primary data centers. I also integrated ACI topology data into ServiceNow using REST APIs and MID Servers to improve network visibility.

At RELIANCE JIO INFOCOMM LTD, I managed enterprise Cisco ACI environments and led data center migrations to an ACI Leaf-Spine topology. Earlier, I worked on network engineering and operations at WIPRO LIMITED, GLOBAL SMS NETWORKS PVT LTD, RELIANCE INDUSTRIES LTD, and VSNL (VIDESH SANCHAR NIGAM LIMITED).
