Problem

Our personalization platform powers product recommendations for millions of users. It needs a continuous feed of user interaction signals - clicks, purchases, saves, and ratings - from multiple product surfaces and a feature computation layer that keeps user profiles current. Different teams own different signal sources and have different latency requirements. Design the ingestion and feature pipeline.
