Enterprise Secure RAG Platform

Built a production-grade Retrieval-Augmented Generation (RAG) platform for secure natural-language querying of organisational knowledge bases using semantic search and vector embeddings. Implemented hybrid retrieval pipeline with Gemini 1.5 embeddings, ChromaDB vector similarity search, and reranking; used GPT-4o-mini, LLaMA 3 (Groq), and OpenRouter as fallback LLMs. Designed Express.js REST API with MongoDB (Mongoose) for session management, document metadata, and audit logging; used BullMQ for asynchronous document ingestion job queues. Engineered security layer with JWT authentication, bcrypt password hashing, prompt-injection detection, PII masking, role-based access control (RBAC), Helmet headers, and API rate limiting.

Library Management System

Developed a console-based application with full CRUD operations and persistent file handling for managing books, members, and borrowing records. Applied object-oriented programming principles for modular and maintainable architecture with clearly separated classes and responsibilities.

Humidity Level Prediction System

Built an end-to-end supervised ML pipeline to predict 3 PM humidity from 9 AM weather data; performed EDA, data cleaning, and feature engineering using Pandas. Trained and evaluated a Decision Tree Classifier with cross-validation, accuracy metrics, and visual analysis to assess model generalisation.
