Follow a complete sequence or jump into the skill you need. Every path combines explanation, practice, and something worth building.
Go Basics
Build a solid mental model of Go syntax, types, functions, structs, interfaces, and errors.
Backend APIs
Move from handlers and routing to complete, tested REST services using the standard library.
Databases
Model data, write reliable queries, manage migrations, and connect Go services to Postgres.
Concurrency
Master goroutines, channels, synchronization, cancellation, and production worker patterns.
Testing
Write table-driven tests, test HTTP services, use benchmarks, and catch races before release.
Deployment
Package services with Docker, configure CI, observe production, and deploy with confidence.
The Go backend roadmap
Move from language fundamentals to services you can build, test, and ship. Select a step to see what you’ll learn.
Continue learning
Build an HTTP Server from Scratch
Routing, timeouts, static files, and graceful shutdown using only net/http.
Go Worker Pool Pattern
Bound concurrency, propagate cancellation, and handle worker errors cleanly.
Go select Statement
Multiplex channel operations and build responsive concurrent programs.
Build a REST API with Go
A complete JSON service with validation, middleware, testing, and graceful shutdown.
Go Mutex and Shared State
Protect shared memory, understand the race detector, and avoid common deadlocks.
sync.WaitGroup in Go
Coordinate goroutines and learn the ownership rules behind reliable shutdown.
