CCIE #23970 | Senior Network Architect | SD-WAN | AI/ML Infrastructure
8+ years designing and deploying SD-WAN solutions. Now building AI GPU clusters and data center networks — from bare metal to distributed training.
- 8+ years in SD-WAN — enterprise design, deployment, and operations
- Design and build RDMA-capable AI training clusters with lossless Ethernet (RoCEv2, PFC/ECN)
- Architect Spine-Leaf data center fabrics with BGP EVPN VXLAN
- Integrate multi-vendor networks (Cisco, NVIDIA Cumulus, Versa SD-WAN)
- Monitor everything with Prometheus + Grafana dashboards
- Automate with Python, Ansible, and Claude Code
Live PFC/ECN/CNP monitoring from my AI GPU cluster — tracking 40M+ ECN packets and 133M+ pause frames
2-Spine / 2-Leaf Clos fabric with Cisco Nexus 9332PQ, RDMA rail design, QoS/PFC/ECN for lossless RoCEv2
| Metric | Result |
