From classic interview problems to production architecture patterns, learn how to design scalable, reliable systems.

System design is the skill that separates senior engineers from junior ones. Our guides cover classic interview problems like designing a URL shortener, chat system, rate limiter, and notification service. Each problem includes requirements gathering, high-level architecture, detailed component design, database schema, API design, and scaling strategies.
Beyond interviews, we cover architecture patterns used in production: microservices vs monolith trade-offs, event-driven architectures, CQRS, event sourcing, clean architecture, and domain-driven design. Our cloud infrastructure guides cover AWS, Vercel, Supabase, and Railway with real deployment configurations.
Security architecture is equally critical. We cover OWASP Top 10 vulnerabilities with code examples, authentication patterns from JWT to passkeys, authorization models including RBAC and ABAC, and API security best practices. Paste your architecture decisions or security configurations into NexusBro QA for expert review.
