01About

Who
am I?

I’m a Computer Science & Engineering undergrad at IIT Indore focused on practical AI, systems design, and building high-performance software.

I like learning how things work under the hood — whether it’s unraveling the complexities of neural networks or diving deep into low-level operating systems.

OpenLeaf

High-concurrency collaborative LaTeX editor built as an open alternative to Overleaf with on-the-fly PDF compilation.

Cloudflare WorkersGoogle CloudLaTeX EngineReactTypeScriptTailwind CSS

Project details

Engineered an independent Overleaf alternative to overcome free-tier platform restrictions and enable unrestricted collaborative document authoring.
Architected a serverless frontend edge-deployed on Cloudflare Workers, interfacing with a containerized Google Cloud backend engine executing secure LaTeX PDF compilation routines on demand.
Designed real-time compilation pipelines optimized for sub-second document previews with multi-user collaborative synchronization.

BeatChain

Interoperable, intermediary-free music streaming platform powered by on-chain micro-payments and decentralized content routing.

SolidityHardhatEthers.jsOpenZeppelinNext.jsPinata IPFSTailwind CSS

Project details

Architected a full-stack Web3 music streaming platform on the Ethereum Sepolia testnet, using Next.js with ethers.js and Pinata IPFS for immutable, decentralized storage of audio assets and metadata.
Engineered a custom suite of OpenZeppelin-secured Solidity smart contracts to coordinate instant ETH tips, ERC-721 collectibles embedded with ERC-2981 standard royalty parameters, and an ERC-20 tokenized governance network for decentralized copyright dispute claims.
Optimized EVM compilation and gas efficiency by replacing standard string require checks with custom error structures (saving ~8,000 gas on deployment) and utilizing low-level calldata pointers to minimize expensive memory allocation routines during track ingestion.

Smart Supply Chain Optimisation

Production-grade logistics routing and vehicle assignment engine driven by Graph ML and Reinforcement Learning.

PythonPyTorchFastAPIWebSocketsGoogle Cloud RunVertex AILeaflet.js

Project details

Architected a supply chain simulation environment mapping 40 Indian logistics hubs, engineering a custom stochastic anomaly engine to inject real-time weather and traffic disruptions.
Trained an end-to-end Heterogeneous Graph Transformer (HGT) and Proximal Policy Optimization (PPO) agent using a 3-phase curriculum, outperforming static greedy baselines in high-volatility scenarios.
Deployed the real-time simulation engine to Google Cloud Run, streaming graph state via WebSockets to a React/Leaflet dashboard, and integrating Vertex AI (Gemini 2.5 Flash) to generate natural-language routing explanations.

IITIbot

A resilient, multi-agent Corrective RAG (CRAG) pipeline designed for low-hallucination institutional knowledge retrieval.

PythonPathwayDockerFastAPIReactRenderVercelLLMs

Project details

Engineered a dynamic, multi-agent RAG chatbot utilizing the Pathway framework's Rust-based engine, indexing unstructured data scraped from ~150 institutional websites and PDFs.
Architected a Corrective RAG (CRAG) pipeline featuring specialized LLM routing and sub-query generation agents to process complex, multi-step queries.
Implemented an automated Critique Agent to evaluate answer relevancy, automatically forcing document re-retrieval and answer regeneration if the confidence score fell below 0.80.
Containerized the agentic backend via Docker, deploying the REST API on Render and a React-based frontend on Vercel.
