The post covers seven major engineering challenges: continuous ingestion via reconciliation loops (not batch jobs), multi-index architectures (relational ground truth, BM25, vector, knowledge graph), retrieval as a dynamic orchestration graph rather than top-k similarity, teaching the brain through curation and usage feedback, agent execution with separate credentials and interrupt/approve flows, an LLM gateway for reliability and cost attribution, and evaluation harnesses with golden datasets. Key principles: treat all indexes as rebuildable projections from a relational source of truth, make identity deterministic and operations idempotent, and build evaluation infrastructure early. The author draws from a production system serving multiple tenants across dozens of data sources. ## Full article daily.dev links to this article rather than hosting it.
