About
I’m Shahid Koul, a Network Engineer at AT&T, working on monitoring, troubleshooting, and maintaining large-scale enterprise networks. I’m passionate about ensuring reliable connectivity, quick incident resolution, and stable network operations in high-availability environments. With a B.Tech in Computer Science Engineering and a strong foundation in networking, I work extensively with routing and switching technologies, including OSPF, BGP, EIGRP, VLANs, STP, EtherChannel, ACLs, NAT, and load balancing. My role involves analyzing Layer 2 and Layer 3 network issues, identifying root causes, and implementing solutions that maintain network performance and uptime. What drives me is the challenge of solving complex network problems in real time. I enjoy diving deep into packet flows, routing behavior, and infrastructure design to ensure networks remain efficient, scalable, and secure. Alongside my professional work, I continuously strengthen my expertise through advanced lab practice and enterprise networking studies, with a focus on routing, switching, and network security. 🎯 Career Goal: To grow into a Level 2/Level 3 Network Engineer and eventually specialize in Network Security, contributing to designing and securing resilient enterprise networks. If you’re working in networking, infrastructure, or security — let’s connect and exchange ideas. 📩 shahidkoul2@gmail.com
