Smart India Hackathon 2026 prototype for a Ministry of Coal problem statement

• Turns mining and geological PDFs, scans, images, CSVs, and spreadsheets into structured, traceable facts.
• Grounded Q&A with page citations, automated report generation with fact checks, topic analysis, and a human review queue for cross-source conflicts.
• 109 passing offline tests. Deployed on Vercel.

GitHubLive site

One chat interface for every model, plus a drop-in OpenAI-compatible gateway

• Self-hosted, provider-agnostic LLM playground on FastAPI, LangChain, and LangGraph. Point it at any provider, model, base URL, or key.
• Live token streaming and per-thread memory over a single interface.
• Exposes an OpenAI-compatible `/v1` endpoint, so existing tools can be pointed at it without changes.

• LangChain
• LangGraph

GitHub

Machine learning that predicts a machine's operating condition from live sensor readings

• Predicts operating condition from sensor data and production KPIs to surface early warning signs of failure, downtime, and quality loss.
• Targets the cases where fixed threshold rules fall short, which is where a rules-based alert is least useful.

• Python
• Machine Learning
• Sensor Analytics

GitHub

An interactive machine learning lab where concepts can be visualised, calculated, and broken

• Each concept is worked through on one page: understood, visualised, calculated, built, experimented on, broken, and practised.
• Built as a static, fast-loading teaching surface rather than a slide deck.

GitHub

Agentic task management that turns a natural-language goal into tracked subtasks

• Understands natural-language goals, decomposes them into subtasks, and processes them with an LLM.
• Persistent contextual memory backed by RAG, so tasks carry context across sessions.
• Full-stack with JWT authentication and password reset. Deployed.

• Next.js
• LangChain
• Supabase
• PostgreSQL
• RAG
• Vercel
• Render

Retrieval augmented analysis over a CSV dataset

• Upload a CSV dataset, query it in natural language, and get context-aware insights.
• Forks from readers who wanted to explore the same dataset, which is the clearest signal that it solved a real problem.

• Python
• LangChain
• FastAPI
• Pandas

GitHub

A minimalist sanctuary for word exploration

• Editorial-grade dictionary experience with mesh gradients, noise overlays, and considered typography.
• Smart typeahead for word lookup, built for reading rather than for speed.

• TypeScript
• Tailwind CSS v4
• Framer Motion

GitHubLive site

An implementation-first ML and AI engineering learning system

• A deeply connected curriculum running from fundamentals through deep learning, NLP, generative AI, and LLMs.
• Continues into RAG, LangChain and LangGraph, AI agents, evaluation, and deployment.
• Built as connected modules and projects rather than isolated notebooks.
