About this project

RAG (Retrieval-Augmented Generation) pipelines are the new data-engineering specialty. This project teaches the full pipeline: document ingestion, chunking strategies, embedding generation, vector storage (pgvector or Qdrant), retrieval, and reranking. Build it on a real corpus — your company's docs, an open-source codebase, Wikipedia subset.

Why build this in 2026?

Every AI product has a RAG pipeline behind it. Data engineers who can build and maintain these have a sharp hiring advantage.
