At Aeronautical Development Establishment (DRDO), I maintain secure LAN/WAN infrastructure across 150+ nodes in a defence-grade environment, sustaining 99.5% uptime.
I manage IP address allocation and DHCP provisioning for 150+ users, and troubleshoot Cisco switches and routers as part of incident and problem-management workflows.
I also administer software licensing and installations across 150+ endpoints, enforce network security policies, and coordinate with vendors on hardware and firmware escalations.
In my lab work, I build network topologies in Cisco Packet Tracer and GNS3, configure OSPF, EIGRP, VLANs and inter-VLAN routing, and analyze packets with Wireshark. I’m pursuing CCNA certification and have foundational exposure to AWS networking and Python.
