Why Spaghetti Code Beat Clean Architecture

The podcast explores the critical lesson that code quality is just one aspect of a successful production system. It recounts an experience where a senior engineer's clean code failed spectacularly due to neglecting infrastructure, observability, and operational culture. The story illustrates how a focus on textbook clean code principles led to overlooking crucial elements like caching, database scaling, and real-time monitoring, which the legacy system had in place. The speaker highlights the importance of considering all four pillars—code quality, infrastructure, observability, and operational culture—to prevent disasters and ensure system resilience, especially under heavy load.
