Explain Your System Architecture evaluates requirements, scale assumptions, API/data design, architecture, trade-offs, failure modes, and rollout in a realistic interview setting. A strong answer states assumptions, handles edge cases, explains trade-offs, and shows how to validate the result clearly.

Question

Explain the end-to-end architecture of a system you built. For each module discuss: how to speed up services, expected QPS, and how Kafka guarantees message delivery, among other considerations.
