🚀 NASA RAG Challenge

AI Quest Hireathon 2026 · i2e Consulting · 70+ Builders

4-layer production RAG over 270-page NASA Systems Engineering Handbook — the "impossible" documentation challenge.

01 → Azure Document Intelligence
     (structural ingestion + tables)
02 → Hybrid Search: Vector + BM25
     (NASA acronym resolution)
03 → Multi-hop Retrieval
     (cross-chapter reasoning)
04 → Precision Citation Engine
     (exact §4.3.2 IDs)

RAG Azure LangChain

🕸️ Enterprise GraphRAG System

Personal Project · Azure AI + Neo4j · 2026

Production GraphRAG combining Neo4j knowledge graphs + Azure OpenAI — multi-hop reasoning that flat vector RAG cannot achieve.

→ Neo4j GDS: entity & relationship graph
→ Cypher + Azure Cognitive Search: hybrid
→ 3× better context than vector-only RAG
→ Docker + MLflow + GitHub Actions CI/CD
