i build rag pipelines

I build production LLM systems, agent workflows and the evals that keep them honest, then the product around them.

  • TCS · RAG test-case generator

    less manual test-writing

    Test scenarios generated from enterprise documents by a local Mistral RAG service.

  • TCS · Figma-to-code agent

    faster screen development

    50–70% shorter build cycles with a multi-agent LangGraph code generator.

02 / About

who builds this.

I build production LLM systems, retrieval pipelines and the evals that keep them honest.

I'm an AI engineer at Tata Consultancy Services (ID&A unit) in Chennai. By day I ship RAG microservices, multi-agent code generators, knowledge-graph experiments and graph-neural-network forecasting for enterprise teams.

Before TCS I was founder-in-residence at Zemuria, leading Kix News, an AI platform that collates sources and checks news for bias. I also mentor teams at TCS AI Fridays, helping them get from idea to working prototype fast.

what I do.

AI engineer building production GenAI: retrieval pipelines, agent systems, fine-tuned and quantized models, and the evals that keep them honest. Full-stack enough to ship the product around the model.

AI + LLM integrations

Retrieval, re-ranking and evals wired into your product, with latency and cost you can see.

  • RAG
  • Re-ranking
  • Pinecone
  • Ragas
  • Grounded answers from your own data
  • Quality tracked with evaluation sets
  • Clear cost and latency numbers
02 / 05

Agent systems

Multi-agent workflows with LangGraph, A2A and MCP servers that plug into Cursor and Copilot.

  • LangGraph
  • A2A
  • FastMCP
  • Guardrails
  • Agents that coordinate on real tasks
  • Tools exposed to the assistants your team already uses
  • Guardrails for security and code standards
03 / 05

Custom web apps

Next.js products with the AI layer threaded through, from first sketch to deployed and instrumented.

  • Next.js
  • FastAPI
  • TypeScript
  • Tailwind
  • Fast, accessible interfaces
  • Typed APIs and validated data
  • Launch with analytics in place

SaaS product build

From MVP scope to role-based dashboards and billing, the way Mark Bot runs content agencies today.

  • Auth
  • Dashboards
  • Billing
  • Deployment
  • A scoped MVP that proves value
  • Role-based access and billing flows
  • A roadmap driven by real usage
05 / 05

Model fine-tuning

Open models adapted to your domain with fine-tuning and RLHF, then quantized to run on your own hardware, plus graph neural networks where the data is a network.

  • Fine-tuning
  • RLHF
  • Quantization
  • GNNs
  • A model that speaks your domain's language
  • Smaller, cheaper models that run on-prem
  • Graph models for networks like rail and logistics

how I work.

  1. Week 1

    Scope

    Define the wedge. Cut anything that does not move a metric or a feeling.

  2. Week 2

    Build

    Production code from day one. UI, API and the AI layer threaded together.

  3. Week 3

    Ship

    Deployed, instrumented, handed over with docs and a roadmap for what comes next.
