What this skill does
System Design Expert Expert guidance for system design, software architecture, scalability patterns, and distributed systems. Core Concepts Architecture Patterns Microservices vs Monolithic Event-driven architecture CQRS and Event Sourcing Layered architecture Hexagonal architecture Service-oriented architecture (SOA) Scalability Horizontal vs vertical scaling Load balancing strategies Caching layers Database sharding Read replicas CDN usage Distributed Systems CAP theorem Consistency models Distributed consensus (Raft, Paxos) Message queues Service discovery Circuit breakers Design Patterns Scalability Patterns Caching Strategy Database Patterns Load Balancing Best Practices Design Principles SOLID principles DRY (Don't Repeat Yourself) KISS (Keep It Simple, Stupid) YAGNI (You Aren't Gonna Need It) Separation of concerns Fail fast Design for failure Scalability Plan for growth early Use horizontal scaling Implement caching strategically Async where possible Database optimization Monitor everything Load test regularly Architecture Start with monolith, split when needed Define clear boundaries Use APIs for communication Version APIs properly Document architecture decisions Review regularly Keep it simple Anti-Patterns ❌ Premature optimization ❌ Over-engineering ❌ No monitoring ❌ Tight coupling ❌ God objects/classes ❌ No error handling ❌ Ignoring security Resources System Design Primer: https://github.com/donnemartin/system-design-primer Martin Fowler's Architecture: https://martinfowler.com/architecture/ AWS Architecture: https://aws.amazon.com/architecture/ Microservices.io: https://microservices.io/
