Backend Development

This is a solid reference for backend fundamentals that covers the stuff you actually need: RESTful API conventions, database schema patterns with UUIDs and soft deletes, JWT authentication middleware, and cache-aside patterns with Redis. It's opinionated in the right ways, like using cursor-based pagination and structured error responses. The code examples are practical and copy-pasteable, from rate limiting setup to observability patterns. Use it when you're designing a new API or need a quick reminder of best practices for auth flows and database indexing. It won't teach you advanced distributed systems, but it nails the core patterns most backend services actually need.
