Golang Backend Development

This is your reference for building production backend systems in Go, covering the full stack from goroutines and channels to web servers and microservices. The skill walks through Go's concurrency primitives with working patterns: goroutines for lightweight threads, channels for communication, select for multiplexing, and context for cancellation. You'll find practical examples of HTTP servers, mutex patterns for shared state, and the core idioms like WaitGroup coordination and the per-connection goroutine model that makes Go servers scale. Use this when you're building APIs, microservices, or anything that needs to handle concurrent requests efficiently. The concurrency section is solid and shows why Go's model is cleaner than callback hell or manual thread management.
