About Me

I am an Applied AI Engineer with 3 years shipping production software, most recently building GenAI systems in production: RAG pipelines, autonomous agents, and MCP tooling. I design, build, and deploy AI products end to end — requirements and architecture through evaluation, deployment, and customer onboarding.

Currently an AI Engineer at Staples, Chennai, working daily with the US product team on agentic retail search over a Neo4j hybrid graph + vector index. Alongside that I run Noetic Laboratories, where I have taken a product from first demo to a signed paying customer solo — Agnihr for labour compliance, and Striketroop, a pre-launch WhatsApp AI CRM for clinics.
