Designing resilient network infrastructure from enterprise backbones to carrier fabrics. I specialize in closed-loop GitOps pipelines, Source of Truth architectures, and automated network state validation.

• 22 Jinja2 Templates: Native SR OS MD-CLI/YANG data hierarchies covering Underlay (IS-IS/OSPF/SR-MPLS), Overlay (MP-BGP), L2VPN (Epipe/VPLS), L3VPN (VPRN/IES), and QoS.
• Concurrency-Safe Deployment: Exclusive whole-pipeline NETCONF candidate locking (sros_lock_candidate) preventing shared candidate collisions.
• Closed-Loop Verification: 6-stage deployment orchestrator (run_verified_deployment.py) featuring pre/post-change pyATS state snapshots, convergence soak, and automatic confirmed-commit rollback on invariant regressions.
• Streaming Telemetry: Containerlab topology integrating gNMI telemetry collection via Telegraf, Prometheus, and a pre-provisioned Grafana dashboard.

• OSPF Series: In-depth architecture breakdown covering single/multi-area topology design, cost metric tuning, and OSPFv3 IPv6.
• NetDevOps & Source of Truth with NetBox: Automated dynamic inventories, Containerlab Infrastructure as Code testbeds, and pyATS state verification.
• Enterprise Routing & Switching: Hands-on implementations of EtherChannel, STP, HSRP gateway failover, and Layer 2 defense-in-depth.
