 This architecture gives you a production-ready ML system that can provide sophisticated intelligence on government funding opportunities, going far beyond simple filtering to offer predictive insights, competitive analysis, and strategic recommendations.

 Perfect! Now I see the full picture. You want to demonstrate your **end-to-end data engineering + ML capabilities** as a proof of concept for potential government data clients.
 **The Strategic Play:** Build a sophisticated ML-powered analysis layer on top of your government funding ETL pipeline to show clients what's possible beyond basic filtering.
