About

I build AI that makes it to production.

Gen AI Developer at TCS. I design and ship end-to-end AI products, from the agentic backend to the interface users actually touch — LangChain, LangGraph, RAG architectures, and multi-model orchestration, with full ownership of deployment on the other end.

Not demos. Shipped products, running in production, used by real people.
The bar I hold myself to
01

End to end

Agentic backend, the interface users touch, and the deployment that keeps both alive. No hand-offs in the middle.

02

Reliable, not impressive

Evals, guardrails, and retrieval that holds up on messy real input — the unglamorous half of shipping AI.

03

Used by people

Shipped and running. Real users, real traffic, real consequences when it goes wrong.

How I got here

The chapters that actually moved the work: platform engineering, then the move into generative AI, then owning agentic systems end to end.

  1. Apr 2026 — PresentCurrent

    Full-stack AI Engineer

    TCS · Bengaluru

    Fully focused on end-to-end Generative AI delivery: agentic backends, RAG pipelines, evaluations, and the interfaces on top. Enterprise knowledge assistants that give employees reliable answers, AI automation that streamlines SDLC workflows, proof-of-concept to production on React, Python, PostgreSQL, Docker, and GitHub Actions.

    Web Developer · AI engineering team

    TCS · Bengaluru

    Embedded in the AI engineering track owning the front end of enterprise GenAI applications: chatbot and knowledge-assistant interfaces, streaming LLM responses, dashboards. Learned the model side from inside the product, and widened the work into the backend along the way.
