About

A flashy LLM demo takes a weekend. An AI agent you can actually run in production — that's the real work.

Full-Stack AI Engineer building LLM-powered, agentic systems with LangChain, LangGraph, RAG, and MCP over Claude (AWS Bedrock) and OpenAI. Proven impact in agent guardrails, LLM observability, and cost optimization — shipping well-tested AI systems on AWS and Azure for enterprise clients in fintech, publishing, and telecom.

I’m a 6+ years Full-Stack AI Engineer based in India, currently a Senior AI Engineer at Edstem Technologies. I care about the unglamorous parts — guardrails, observability, cost, and test coverage — because that’s what separates a demo from a system you can trust in production.
