📚 RAG Chatbot — Chat with ML Notes

Retrieval-Augmented Generation over a custom knowledge base. Embeds documents, retrieves relevant chunks by semantic similarity, and answers with sources shown — plus an "I don't know" fallback instead of hallucinating.

📊 Customer Churn Prediction API

A Random Forest pipeline — preprocessing + model saved as one artifact — served as a production FastAPI service. Pydantic validation, pytest test-suite, Docker packaging, interactive demo. Deployed via GitHub → Render.

🕵️ Credit Card Fraud Detection API

Random Forest + SMOTE on 284k transactions (0.17% fraud) — because accuracy means nothing on imbalanced data. Compares 4 approaches, deploys the winner, and explains every flag with SHAP values.
