Enterprise data hub connecting 14 sources with intelligent query routing using CAG, RAG, and GraphRAG technologies managed by AI agents based on query complexity.
Python · LangChain · Neo4j · PostgreSQL · Pinecone · Claude · Apache Kafka · FastAPI · Redis · dbt
The project was delivered in four stages over six months, building the data foundation first, then implementing progressively sophisticated retrieval methods.
| Stage | Focus Area | Status | Key Deliverables |
|---|---|---|---|
| 1 | Data Infrastructure | Completed | PostgreSQL warehouse, Kafka streaming, CDC pipelines for ERP/CRM/billing, data normalization, identity resolution across systems |
| 2 | CAG Implementation | Completed | Redis caching layer, frequently-accessed data preloading, context window optimization, sub-100ms response for common queries |
| 3 | RAG & GraphRAG | Completed | Pinecone vector store, Neo4j knowledge graph, entity extraction, relationship mapping, semantic search across documents |
| 4 | Agent Orchestration | Completed | Query complexity classifier, intelligent routing system, response synthesis, natural language interface, feedback learning loop |
