## About

```text
At SK Jalrakshak Innovations (SKJAL), I segmented the production office LAN into departmental VLANs, configured 802.1Q trunks and EtherChannel, and tuned RPVST+ on Cisco IOS.

I restored subnet reachability by correcting routing errors, then deployed static, default, and single-area OSPF routing. I also secured the access layer and used Wireshark captures to diagnose connectivity failures.

In my Cisco Packet Tracer labs, I document configurations, verification results, and fault logs. I'm seeking an entry-level Network Engineer, NOC Engineer, or Network Support role.
