I build production GenAI systems, and the evidence that they work.

  • RAG systems
  • agentic workflows
  • LLM evaluation
  • vector search
  • prompt engineering

I'm an AI Engineer at Orion Innovation in Chennai, working there since November 2024. I build retrieval-augmented generation pipelines, agentic workflows and LLM evaluation for enterprise clients, including a financial document intelligence system and an internal HR knowledge assistant. Outside work I build projects to test ideas end to end, such as a deep research agent, an LLM benchmarking framework and a hallucination detector.

MicroManus

Investigator visibilis

Deep research AI agent

A full-stack deep research agent with a visible reasoning loop, so users see the model's multi-step research and tool use as it happens. Built without LangChain or LangGraph, and live.

read the plate
  • Added social login with OAuth and usage-based billing using Supabase and Stripe, for production-ready onboarding and metered monetization.
  • Designed a bring-your-own-key system that encrypts user-provided API keys with AES-256-GCM, giving self-managed access to multiple LLM providers.
  • Integrated SerpAPI for live web search grounding and deployed on Vercel as a public product.
