LLM Applications Agentic Systems Full-Stack Engineering ML Pipelines LLM Applications

Building systems that think — from raw model to production product.

01 — About

Craft at the intersection
of code and cognition.

I build AI-powered products that go beyond demos — production-ready systems with reliable inference, thoughtful UX, and clean APIs. My background spans distributed systems, LLM orchestration, and the full web stack.

I believe the most interesting engineering happens when language models meet real constraints: latency budgets, cost ceilings, imperfect data, and actual users. That's where good architecture matters.

Currently based in Pune, MH — open to remote-first teams working on meaningful AI problems.

Things I've shipped.

AI Web Open Source

DocMind

Open-source RAG framework for building agentic LLM applications.

DocMind is a Retrieval-Augmented Generation (RAG) application that enables users to upload one or more PDF documents and interact with them through a conversational interface. The system uses semantic search to retrieve the most relevant document chunks and leverages a Large Language Model (LLM) to generate accurate, context-aware answers with source citations.

ResearchAgent

Autonomous multi-step research agent powered by LangGraph and live web search.

A stateful agent that plans, searches, reads, and synthesizes multi-source reports on any topic. Includes a human-in-the-loop approval step and exports to Markdown.
