System Goal

Build a retrieval-augmented generation system that answers domain-specific questions using a controlled document collection, with explicit evaluation for retrieval quality, groundedness, and answer usefulness.

Why This Demonstrates Expertise

A credible RAG project is more than a chat interface. It should show how documents are chunked, embedded, indexed, retrieved, reranked, cited, evaluated, monitored, and improved.

Architecture

Planned components:

  • Document ingestion and cleaning.
  • Chunking strategy and metadata schema.
  • Embedding model selection.
  • Vector database, such as FAISS or Pinecone.
  • Retrieval and reranking.
  • Response generation with citation constraints.
  • Automated evaluation dataset.
  • Hallucination and groundedness checks.
  • Drift and regression monitoring with LangSmith or Langfuse.

Evaluation Plan

Track:

  • Retrieval recall at k.
  • Context precision.
  • Citation support.
  • Faithfulness or groundedness.
  • Answer relevance.
  • Latency and cost.
  • Regression performance across prompt, model, and retrieval changes.

Executive Summary Template

Replace this with a concise system readout: what the system does, where it performs well, where it fails, and what monitoring is required before deployment.
