Document Q&A Chatbot with RAG Pipeline

Junior20-35h

Build a simple question-answering chatbot that ingests PDF or text documents, chunks and embeds them into a vector store (e.g., ChromaDB or FAISS), and uses an LLM (e.g., OpenAI GPT or HuggingFace model) to answer user queries based on retrieved context. Implement a basic Python CLI or Gradio UI for interaction.

Scalable Multi-Agent RAG System with Distributed Document Processing

Mid-level60-90h

Design and implement a distributed RAG system where document ingestion and embedding generation are handled by parallel workers using a task queue (e.g., Celery with Redis). Deploy multiple LLM inference agents that handle concurrent user queries, implement semantic caching to reduce redundant LLM calls, and add an evaluation pipeline using RAGAS or custom metrics to measure retrieval accuracy and answer faithfulness. Expose the system via a REST API.
