With around 2 years of industry experience in network administration, I specialize in managing and configuring Cisco routers, Cisco Layer 2/Layer 3 switches, and Checkpoint firewalls. I have strong hands-on expertise in routing protocols including RIP, IGRP, EIGRP, OSPF (multi-area), and BGP, enabling efficient and secure network operations. Currently, I am working at Tata Consultancy Services (TCS), where I contribute to maintaining robust network infrastructure and ensuring high availability and performance.
