Production RAG: FAISS, BM25 & Reciprocal Rank Fusion
Building a production-grade RAG pipeline from scratch: dense embeddings, BM25 lexical search, RRF rank fusion, cross-encoder reranking, and quantitative Ragas hallucination evaluation.
Production guides on building reliable LLM systems: hybrid dense/sparse RAG cascades, cyclic LangGraph state machines, deterministic guardrails, and enterprise Document AI platforms.
Building enterprise Generative AI requires treating language models as reasoning primitives within deterministic software harnesses. Reliable production applications demand structured JSON schemas, cyclical state graphs with human-in-the-loop checkpoints, and hybrid vector/lexical retrieval evaluated through quantitative metrics like Ragas. Explore the engineering blueprints below.
