AI/ML engineer building RAG systems with LangGraph, NeMo Guardrails, and Portkey.

At CDAC, I designed telecom traffic data storage with Berkeley DB and implemented structured retrieval mechanisms to improve data access efficiency.

I built NEUROASSIST, a RAG system using LangGraph for agentic workflows, multi-step reasoning, and history-aware query planning. I added NeMo Guardrails to block unsafe queries and integrated Portkey with Groq API key fallbacks for reliable inference.
