I build production-grade systems — multi-agent LLM pipelines, 3D web experiences, data infrastructure, and full-stack products. End to end.

About

I build things
end to end.

I'm a 2024 ECE graduate from NIT Srinagar, based in Bengaluru. My work spans AI application engineering, backend systems, data infrastructure, and frontend — I'm most comfortable when I own the full stack.

At Sigmoid Analytics, I completed a six-month structured training program across the modern data and DevOps stack, then built a production multi-agent LLM system from scratch in 24 days. Before that, I shipped three full-stack personal projects spanning a real-time social graph, a Stripe-integrated e-commerce platform, and a 3D configurator with physics simulation.

I care about systems that are observable, honest about their limits, and maintainable by people who weren't there when they were built.

Production LLM · FastAPI · LangGraph

Intent router dispatching to 3 specialist agents — product search, order tracking, support escalation. Deterministic safety gates keep auth and cancellation logic in Python, never in the LLM. 5-step query relaxation, tier-based ranker, full observability. Built in 24 days.

Where I've worked.

7 months at Sigmoid Analytics — structured training, then a production capstone.

DataOps Intern
Sigmoid Analytics
November 2025 – June 2026

A six-month structured engineering rotation across the modern cloud, data, and AI stack — followed by a solo production capstone taken from blank repo to a deployed, observable system.
