Go has become one of the most popular languages for building backend services. It is fast, quick to learn, and powers tools like Docker, Kubernetes, and a large share of modern cloud infrastructure. This course takes you from your very first line of Go to a real, working backend service. If you can already code a little in another language, you are ready. We start with the Go language itself (types, structs, interfaces, slices, maps, errors, and goroutines), then build a complete Task API step by step: an HTTP server with the standard library, JSON endpoints and context-aware handlers, request validation, a test suite (httptest, table-driven, and integration), a PostgreSQL database, production essentials (configuration, structured logging, graceful shutdown), and a multi-stage Docker build to ship it. By the end you will not just know Go syntax. You will have built a backend service the way it is done in production, and you will understand why each piece is there.

Developers who are new to Go, can already code a little in another language, and want to build real backend services.
