Full Stack Engineering Series #13 - System Design | 3-Tier Architecture, N+1 Problem & Indexes

Description In this episode of the Full Stack Engineering Series, we explore important system design and performance concepts used in real-world applications. This video covers architectural patterns and optimization techniques that every backend and full stack engineer should understand when building scalable systems. Topics covered • 3-Tier Architecture Pattern Presentation Layer Application Layer Data Layer Why this architecture is widely used in modern systems • N+1 Query Problem What causes it Why it hurts performance How to detect and fix it • Caching Strategies Application caching Database caching Reducing latency and database load • Background Jobs Offloading heavy tasks from request-response cycles Examples: emails, image processing, analytics jobs • EXPLAIN ANALYZE Understanding database query execution plans Finding slow queries Optimizing database performance These concepts are critical for designing high-performance systems and are commonly discussed in system design interviews and production backend systems.
