Protecting India's 12 million gig delivery workers from income loss during disasters

When a flood, AQI spike, or curfew hits, KAVACH's AI predicts exactly how much a delivery worker would have earned — and pays them automatically within minutes via UPI. No forms. No waiting.

What makes it extraordinary:

• 🧠 Stacked ML ensemble (XGBoost + LightGBM + Ridge) — R² 0.9874, MAE ₹16.79, trained on 60,000 samples
• 🔗 Blockchain audit trail — every payout hashed & logged immutably on Sepolia ETH (Etherscan-verifiable)
• 🚦 7-layer fraud engine + Physical Presence Confidence Score (PPCS) — detects GPS spoofing rings
• 📡 Multi-source parametric triggers — rain, AQI, flood, curfew, platform outage across 16 Indian cities
• 💸 Zero-touch payouts via Razorpay UPI within minutes of disruption detection
• 🌍 Multilingual PWA — English, Hindi, Tamil with Claude AI chatbot built-in

Farm to consumer transparency — eliminating middlemen, empowering farmers

A decentralized platform where farmers create product batches on-chain, transporters update states, retailers purchase with automated payment splits — and consumers scan a QR code to see the full journey of their food.

Key features:

• ⛓️ Smart contract on Sepolia ETH with role-based access (Farmer / Transporter / Middleman / Retailer / Consumer)
• 💰 Automated payment distribution on purchase — no middleman can intercept farmer pay
• 📱 QR code traceability — consumers see every hand the product passed through
• 🔒 OpenZeppelin AccessControl + ReentrancyGuard — production-grade security

My very first Python project. Built in 12th grade with two friends.

A single-elimination bracket tournament simulator in pure Python — before I knew about frameworks, APIs, or any best practices. Raw, real, and where the journey began.

"A lot of extra code and inefficiency is there... I completed this in my 12th grade with the help of my 2 friends Vishnunath and Dhishaj."
