   Production-Grade Network Automation & Fabric EngineeringLed end-to-end deployment and full validation of Cisco NDFC in a VMware-based lab, building production-style data center fabrics including OSPF/BGP underlay, VXLAN EVPN overlay, L3VNI, and VPC architectures.Designed and implemented a scalable configuration-generation pipeline using Python, YAML, and Jinja2 to dynamically render multi-vendor device configurations and test scenarios.Developed infrastructure-as-code style automation workflows integrating Ansible and Ixia VE for automated provisioning, validation, and certification testing.Built automated pre/post-deployment validation and failover test frameworks using Robot Framework and Ixia APIs, improving test coverage and reliability under scale and failure conditions. API-Driven Automation & Multi-Vendor IntegrationAutomated certification testing across Cisco NX-OS, Arista EOS, F5, and A10 platforms using REST APIs and CLI abstraction layers.Integrated API-driven test orchestration with reusable automation modules and templated pipelines.Performed Layer 1–3 troubleshooting (optics, BGP sessions, routing convergence, failover behavior) using Wireshark and CLI diagnostics to validate fabric stability. Platform Reliability & Engineering OwnershipDesigned reusable automation modules and standardized workflows to improve scalability and reproducibility across lab environments.Authored detailed documentation covering automation pipelines, test architecture, and deployment processes; presented technical findings to engineering teams.Collaborated cross-functionally with network and platform teams to improve reliability, testing depth, and deployment consistency.
