- Led end-to-end troubleshooting of complex production network issues across cloud, datacenter, enterprise, and ISP environments, driving incidents from initial investigation through root cause analysis, service restoration, and permanent corrective action.
- Designed, deployed, configured, and troubleshot large-scale network infrastructure with a focus on high availability, scalability, resiliency, and operational stability.
- Troubleshot Layer 2 and Layer 3 technologies including TCP/IP, ICMP, ARP, BGP (RFC 4271), DHCP, 1G/10G Ethernet (IEEE 802.3ab & IEEE 802.3ae), IPv4, LACP, LLDP, MPLS, NAT, OSPF (RFC 2328), RIP, SNMP, STP/RSTP/MST (IEEE 802.1d), BFD, MLAG/MC-LAG, VARP/VRRP, VLAN (IEEE 802.1Q), VRF, and VXLAN.
- Configured and troubleshot Juniper, Cisco, and Arista routers and switches, analyzing routing tables, ARP/MAC tables, interface counters, device logs, packet captures, and network telemetry to isolate hardware, software, configuration, and connectivity issues.
- Investigated routing failures, packet loss, latency, interface errors, traffic anomalies, and service connectivity issues, performing detailed root cause analysis (RCA) and implementing corrective and preventive actions to restore and improve network reliability.
- Analyzed production network environments, including network topology, configurations, routing behavior, redundancy, capacity, traffic patterns, and infrastructure dependencies, to identify business impact and accelerate issue resolution.
- Performed network testing, troubleshooting, and validation during deployment, firmware qualification, regression testing, release validation, and post-implementation activities, ensuring network readiness and operational stability.
- Built automated network testing and pre/post-deployment validation workflows using Python, REST APIs, and Git, validating configuration consistency, routing protocol state, device reachability, interface health, route programming, service connectivity, and failure scenarios.
- Supported complex technical escalations by collaborating with network engineering, SRE, datacenter operations, security, cloud engineering, and hardware vendors, coordinating investigations and driving critical issues to resolution.
- Participated in network architecture, design, code, and test-plan reviews, evaluating solutions for scalability, high availability, reliability, performance, security, and operational readiness.
- Developed HLDs and LLDs covering network topology, IP addressing, routing, physical connectivity, redundancy, capacity planning, telemetry, and operational requirements, supporting successful testing and production deployment.
- Managed network capacity and performance by analyzing bandwidth utilization, throughput, latency, traffic patterns, port capacity, and infrastructure constraints to identify bottlenecks and recommend scaling requirements.
- Documented troubleshooting findings, RCA, corrective actions, deployment results, and operational procedures to support knowledge sharing, technical documentation, service improvement, and consistent troubleshooting practices.
