Associate Director — Enterprise Cloud & AI Advisory 18+ years. WiMAX rooftops in Delhi → Two Tier-3 DCs built from dust → VMware SDDC → Azure Landing Zones → Agentic AI on the edge. Building "Digital Cathedrals" of code, cloud, and cognition.
In 2006 I was selling credit cards door-to-door. Literally. Not metaphorically. I needed to become someone worth choosing, so I moved alone to Jaipur — call center nights, English class mornings, CCNA labs at midnight.
2009 → Iron Age: Climbing Delhi rooftops in 45°C heat aligning WiMAX antennas by hand (-82 dBm / 12 dB SNR). Learning BGP the hard way. 2011 → The DC Era: Built 2 Tier-3 Data Centers from empty warehouses. PAC thermal management, MP-BGP IPv6, Linux P2V migrations. Nobody taught me how. 2014 → Security Layer: Cisco ASA → Palo Alto App-ID. iRules on F5 LTM. Netmiko automation. 2017 → SDDC & SDN: VMware NSX, HCX live migrations, GENEVE vs VXLAN debates at 2am, Arista OVSDB bridges. 2023 → Now: Azure Enterprise Landing Zones + Agentic AI. Stateful circuit breakers. Vector RAG. Edge inference on Cloudflare Workers AI.
Complexity is the Enemy. Always.
| Metric | Value |
|---|---|
| ⏱️ Years in infrastructure | 18+ |
| 🏢 Employers across 3 eras | 6 (HCL → Spectranet → Net4 → Wipro → IBM → NTT Data → Now) |
| 🏗️ Tier-3 DCs built from scratch | 2 |
| ☁️ VMs migrated to cloud | 1,000s (HCX bulk live, zero downtime) |
| 🤖 AI agents in production | 3 (Digital Twin, Circuit Breaker, Cost Router) |
| 🌐 BGP ASNs configured | More than I can count. Fewer incidents than you'd expect. |
- ⚡ agentic-circuit-breaker: Zero-dependency TypeScript stateful circuit breaker pattern engineered for Agentic AI workflows and LLM API routing. No deps. No drama.
- 💰 llm-cost-router: BGP-inspired Local Preference routing engine for multi-agent LLM cost optimization and cascading model fallback.
- 🏗️ VMware-SDDC-LAB: Infrastructure-as-code Ansible automation pipeline for deploying a full nested VMware SDDC & NSX-T lab. The playbook I wish existed in 2017.
