The Senior Engineer's System Design Cheat Sheet — 40 Patterns for Interviews and Production
System design interviews are the hardest part of senior-level hiring. Most candidates either over-engineer or under-explain. The Senior Engineer's System Design Cheat Sheet gives you 40 patterns that you can combine and adapt for any system design question — from URL shortener to distributed database design. What's inside: 12 Architectural Patterns — microservices, event-driven, CQRS, saga pattern, event sourcing, and when each one is the wrong choice (this matters more than knowing when it's right) 10 Scaling Patterns — horizontal vs vertical scaling, load balancing strategies, database sharding, caching layers, and the CAP theorem trade-offs interviewers test for 10 Communication Patterns — REST vs gRPC vs GraphQL, message queues, pub/sub, WebSocket patterns, and the latency/bandwidth/coupling trade-offs 8 Reliability Patterns — circuit breakers, bulkheads, rate limiting, idempotency, retry with backoff, and the failure modes that kill production systems Who this is for: Mid-level engineers prepping for senior/staff interviews. Senior engineers who want a structured approach to system design questions. Anyone who freezes when asked "design a Twitter" in a 45-minute interview. Format: Instant PDF download.
