In this backend-focused Go (Golang) Full Course (2026), we’ll go from zero → real projects using Go 1.25, clean folder structure, and production-style patterns (without unnecessary complexity).
What we’ll build
⚙️ Core Go foundations (types, control flow, slices/maps, functions)
📦 Real project structure (modules + packages that make sense)
🌐 HTTP server with net/http + JSON APIs
📡 HTTP client + JSON unmarshal from a public API
📝 Project 1: Gin + MongoDB Notes API (CRUD)
🔐 Project 2: Auth + Roles (JWT) + Cloudinary file upload
⚡ Concurrency essentials (goroutines, channels, context, sync)
Everything is taught step-by-step with practical examples you’ll actually use in backend development.
