Our stack uses Python, scikit-learn, TensorFlow, Airflow, and AWS for deployment. Describe two past projects that map to this stack: which components align, why you chose particular libraries or infra, and what trade-offs you faced (accuracy vs. latency vs. cost). Include approximate data sizes and latency constraints from those projects.

Design an architecture to serve personalized ML predictions with a p95 latency target of 10ms globally. Address feature storage and retrieval, model serving (quantization, batching), edge caching, consistency between training and serving features, deployment strategy (multi-region), and failover. Discuss trade-offs between accuracy, freshness, and cost.
