What I'm looking for

I’m looking for a career in the telecommunication and networking industry where I can use and further develop my skills while contributing to the growth of the company and my own career.

At HCL Technologies, I worked with American Express on deploying and configuring new routers, completing router refreshes and site activations, and supporting LAN and WAN changes.

I supported troubleshooting across LAN/WAN, EtherChannel, STP, BGP, OSPF, and hardware issues. I also supported architectural design changes across global sites and worked on Viptela SD-WAN activations and failover testing with Primark.

Previously, at Dell Technologies, I configured campus and data center switches, performed OS upgrades, and supported smartfabric switches in a VxRail environment. At Ericsson Global India Limited, I supported Sprint network migrations from Ciena switches to Cisco ASR 900 series routers and troubleshot connectivity issues.
