Design a Twitter-like platform. Your document should cover scalability, caching, databases, and API design.

1. Requirements — functional and non-functional

2. High-level design — load balancers, app servers, databases

3. Data model — users, tweets, follows, timelines

4. API design — endpoints and request/response shapes

5. Scalability — caching, sharding, read replicas

6. Trade-offs — consistency vs availability, cost vs complexity

Write a full system design document in the editor. Aim for clarity, not perfect answers.
