Backend Patterns

This is a reference collection for common backend architecture patterns, covering REST API design, database strategies, caching, authentication flows, and microservices patterns. You'd reach for this when you're setting up a new service and want to follow established conventions instead of reinventing structure. It's more of a quick lookup than deep tutorial material. The code snippets show clean examples of things like resource-based URL design and repository patterns. Worth having around if you're the kind of person who likes to verify you're doing the standard thing, though experienced backend developers will recognize most of these patterns already. The 27k GitHub stars suggest it's hitting a need for structured reference material.
