About

I'm a Senior AI/ML Technical Product Manager and Applied AI Strategist at Verizon, working at the intersection of LLMOps, data engineering, and product intelligence. My work involves building enterprise-grade AI infrastructure that teams actually use — not demos that die in staging, but production systems that move customer experience metrics and generate IP.

My foundation is statistical — Masters in Statistics from the University of Madras — which means I don't just ship models, I validate them rigorously. I've designed custom statistical test cases that caught model drift before it reached production, and built LLM evaluation pipelines from scratch.

At Verizon, I built ConvoIQ — an LLM-powered conversational intelligence platform analyzing millions of agent-customer interactions. Before that, at Mr. Cooper, I built RAG-powered chatbots, FastAPI PII masking endpoints, and multi-class NLP routing systems. Outside work: 3× US Patent holder (AI-driven customer intelligence, via Verizon).

I offer freelance services in LLMOps Architecture, Statistical Consulting, Agentic AI Engineering, and ML Product Strategy.
