Q: What is the "AI-Powered WhatsApp Chatbot with RAG Architecture" project?

A production-ready AI WhatsApp chatbot using RAG, asynchronous processing, and vector search for context-aware responses.. It was created by PrepLinc Official, a student developer, as a portfolio piece. Read the full project details on PrepLinc.

Overview

I built and deployed a production-grade AI-powered WhatsApp chatbot that uses Retrieval-Augmented Generation (RAG) to generate context-aware responses from custom knowledge bases. The system integrates WhatsApp webhooks with a FastAPI backend and asynchronous workers for reliable message processing.

Key Features

WhatsApp Integration: Integrated WhatsApp Business API webhooks using WAHA for receiving and processing user messages.
RAG Pipeline: Built a Retrieval-Augmented Generation pipeline using embeddings and Qdrant for semantic search across custom knowledge bases.
Asynchronous Processing: Used Redis and queue-based background workers to handle chatbot requests efficiently and improve responsiveness.
Context-Aware Responses: Retrieved relevant information from vector databases before generating responses, enabling the chatbot to answer using domain-specific knowledge.
Production Deployment: Containerized the application using Docker Compose for consistent and reproducible deployments.
Secure Access: Deployed the system behind a Cloudflare Tunnel, avoiding direct exposure of public application endpoints.
Monitoring & Reliability: Implemented retries and queue-based processing to improve reliability during message ingestion and response generation.
