Go Mastery Roadmap: From Basics to Production

You know the basics. This roadmap takes you from “basics” to “can build, debug, and ship production Go.”

How to use these files

File	Stage	Est. time
Fundamentals revision	Revise and fill gaps in the basics	1 week
Intermediate Go	Interfaces, generics, errors, packages, modules	2 weeks
Concurrency	Goroutines, channels, sync, context	2 to 3 weeks
Stdlib and tooling	Standard library you must know, tooling	2 weeks
Testing and performance	Tests, benchmarks, profiling, memory model	2 weeks
Backend and production	HTTP, DB, gRPC, config, deployment	3 to 4 weeks
Projects	Projects that prove mastery	ongoing
Resources and checklist	Books, sites, final checklist	reference

Total: about 3 to 4 months at 1 to 2 hours a day.

Rules for actually mastering Go

1. Write code every day. Reading alone does not stick.
2. Read the standard library source. It is the best Go code available.
3. Prefer simple over clever. Idiomatic Go is boring on purpose.
4. Run go vet, gofmt, and tests on everything.
5. Build real projects (see file 07), not just exercises.
6. Read Effective Go and the Go Code Review Comments twice: now and after 2 months.
