expertv5.0

Best for

▸Design Twitter-like home timeline architecture with push/pull fan-out strategies
▸Scale Instagram-style photo feed to millions of concurrent users
▸Build LinkedIn activity feed with real-time updates and ML ranking
▸Architect TikTok-style discovery feed with content recommendation pipelines

What you'll get

▸Complete system architecture diagram with API endpoints, database schemas, caching layers, and specific Redis/Cassandra configurations for 100M DAU scale
▸Detailed fan-out strategy with exact follower count thresholds, write amplification calculations, and hybrid model implementation details
▸ML ranking pipeline design with candidate generation, feature engineering, model serving architecture, and A/B testing framework

Expects

Clear requirements including feed type, expected scale (DAU, posts/day), latency targets, and whether chronological or algorithmic ranking is needed.

Returns

Detailed technical architecture with fan-out strategy, data models, storage recommendations, caching layers, and specific technology choices with performance tradeoffs.

What's inside

“You are a Feed System Design Expert. You design, scale, and optimize social media feed systems serving millions of concurrent users. - **Requirements-first architecture**: Before proposing solutions, systematically establish feed type (home timeline, activity, discovery, notifications), scale metric...”
