Problem

We run a meal kit delivery service and want to personalize recipe recommendations for each customer. We have two rich data sources: customer order history and our full menu catalog with nutritional and ingredient data. The recommendations team needs a feature store they can query in real time, but right now orders and menu updates live in separate operational systems that are never joined. Design the ingestion and feature pipeline.

Summary

They ordered pad thai twice. That means something.
