The RAG Engineer

Retrieval systems agents can trust in production, beyond the demo

Your RAG demo works. Production is where it breaks.

Embedding a PDF is a demo; surviving production is engineering. The RAG Engineer takes you past the tutorials into the failure modes that actually break retrieval — chunking, freshness, reranking, grounding, and silent drift — with a protocol for pipelines agents can depend on.

• The GRAIN protocol: Gather, Rank, Assemble, Inspect, Navigate
• Fix chunking, freshness, hybrid search, reranking and grounding
• Retrieval pipelines agents can trust in production
