Application design is the hidden skill that separates codebases that scale from ones that collapse — and most developers never formally learn it. They pick up languages, frameworks, and tools. But the underlying structure of how an application is organised? That's usually left to chance. Here's a story you'll recognise. A small team builds a web app fast. It works. Everyone's proud.
