What You Can Do

You'll design complete RAG architectures from ingestion through inference, making strategic decisions on chunking strategies, embedding models, vector database selection, and retrieval tuning. This skill guides you through all five core pipeline phases—document preprocessing, semantic embedding, vector storage, ranking optimization, and context window assembly—ensuring your system balances accuracy, latency, and cost for domain-specific knowledge retrieval at scale.

Features

Document Chunking Strategy

Design semantic-aware splitting with overlap, handling different document types (PDFs, markdown, structured data)

Embedding Model Selection

Choose between dense embeddings (OpenAI, Cohere, open-source) based on cost, latency, and domain fit

Vector Store Architecture

Evaluate and configure PostgreSQL pgvector, Pinecone, Weaviate, Chroma, or Milvus for scalable retrieval

Retrieval Tuning

Implement hybrid search, BM25 + semantic fusion, re-ranking, and metadata filtering to maximize relevance

Context Window Optimization

Intelligently pack retrieved chunks within token limits while preserving semantic coherence

Framework Integration

Deploy via LangChain, LlamaIndex, or custom Python implementations with minimal scaffolding

Evaluation & Iteration

Design metrics for retrieval quality (NDCG, MRR) and end-to-end answer accuracy

Example Output

Example 1: E-commerce Product Support RAG

  • Chunking: 256-token sections from product manuals with 64-token overlap, preserving section headers
  • Embedding: OpenAI text-embedding-3-small for cost efficiency
  • Vector Store: Pinecone with product category metadata filtering
  • Retrieval: Hybrid (BM25 + semantic) with MMR reranking for diversity
  • Output: Customer service bot retrieving exact product specs with 94% accuracy on FAQ queries

Example 2: Legal Document Discovery System

  • Chunking: Clause-aware segmentation respecting legal document structure
  • Embedding: Self-hosted sentence-transformers for data sovereignty
  • Vector Store: PostgreSQL pgvector for on-premise deployment
  • Retrieval: Dense passage retrieval + legal metadata filters (document type, jurisdiction, date range)
  • Output: Paralegal tool surfacing relevant precedents in 200ms with full citation trails
