RAG Chatbot Case Study

RAG Chatbot System

Production AI System for Context-Aware Responses

Role: Technical Product Owner & Developer

Type: Personal Project / Production System

Status: Live & Serving Users


The Challenge

Traditional chatbots and even modern LLMs struggle to provide accurate, context-aware responses about proprietary or specialized data. Users asking questions about specific content receive generic answers that lack the depth and accuracy needed for meaningful engagement.

Key Problem: How do you enable an AI to provide accurate, contextual answers about your own data without the hallucinations and generic responses typical of base LLM models?


The Solution

I designed and built a complete Retrieval-Augmented Generation (RAG) system from the ground up, implementing the full technology stack:

Technology Architecture

Backend

  • FastAPI: High-performance Python API framework
  • Ollama: Local LLM inference engine
  • bge-m3: State-of-the-art embedding model
  • Qdrant: Vector database for semantic search

Infrastructure

  • Docker: Containerized deployment
  • Docker Compose: Multi-service orchestration
  • Nginx: Reverse proxy & SSL termination
  • WordPress: Frontend integration

How It Works

  1. Document Ingestion: Content is chunked and processed through the embedding model
  2. Vector Storage: Embeddings are stored in Qdrant for efficient similarity search
  3. Query Processing: User questions are embedded and matched against stored vectors
  4. Context Retrieval: Most relevant document chunks are retrieved
  5. Response Generation: LLM generates answers using retrieved context

The Results

✅ Production Ready

Live system serving real users with context-aware responses

🎯 Accurate Answers

Responses grounded in actual proprietary content, reducing hallucinations
