👨🏻💻 Meet Lumina – my personal chatbot assistant designed to answer any questions, either about me or any other topics. Powered by Retrieval-Augmented Generation (RAG), LangChain, kNN cosine similarilty search, and Pinecone vector database, Lumina offers intelligent, accurate, and speedy responses tailored for all conversations.
Built on a full-stack architecture with React + Express/Node.js backend, the system implements real-time streaming responses via Server-Sent Events (SSE) and supports conversation branching through message editing with automatic history truncation. Features include JWT-based authentication with MongoDB for persistent conversation storage, an MCP (Model Context Protocol) server for extensible tool integration, and an agentic AI pipeline that combines multiple LLM providers (OpenAI, Google AI). Deployment spans Vercel, Netlify, Docker containers, and AWS infrastructure with Terraform IaC and CI/CD via GitHub Actions.
