At Circana, I build agentic AI platforms that turn retail data into actionable business insights in minutes. My data storytelling engine systematized 70% of recurring analytics reporting and reduced data-to-insight time by 60%.

I design multi-agent workflows for SQL generation, KPI analysis, retrieval, validation, and narrative generation using LangGraph. I improved insight accuracy by 28% with hybrid RAG and reduced API spend by 47% through model routing, prompt caching, and semantic caching.

I also built a multi-tenant compliance Q&A platform for 10,000+ regulatory documents, combining GraphRAG, vector retrieval, reranking, and cited multi-hop reasoning. The platform cut hallucinations by 35%, improved context precision from 0.71 to 0.89, and reduced latency by 40%.

Previously at Harman Connected Services, I built self-hosted LLM serving and AI-driven PostgreSQL automation platforms. I reduced inference costs by 60%, improved throughput by 3x, and built self-healing observability and incident diagnostics for production infrastructure.
