Professional Go (Golang): Advanced Techniques

The book "Professional Go (Golang): Advanced Techniques" is a practical guide for developers who have already mastered the basics of the Go language and want to move to the next level. The author, experienced backend engineer Artyom Sokolov, shares real-world cases and techniques that are not found in the official documentation.

What is this book about?

The book covers key aspects of professional Go development:

• Concurrency and Parallelism — deep dive into goroutines, channels, synchronization primitives (sync.Mutex, sync.WaitGroup) and management patterns (fan-in, fan-out, worker pool).
• Advanced Work with Interfaces — composition, empty interfaces, type assertion, code generation, and creating flexible abstractions.
• Performance Optimization — profiling (pprof, trace), allocations, working with the garbage collector, benchmarks, and writing efficient code.
• Testing and Code Quality — unit tests, table-driven tests, mocks, integration testing, fuzzing, and static analysis.
• Architecture and Design Patterns — dependency injection (DI), repository, factory, strategy, as well as building microservices and monoliths.
• Working with Databases — advanced queries, connection pools, transactions, migrations, and ORM alternatives.
• Security — error handling, race condition protection, working with secrets, and safe serialization.

Who is this book for?

• Go developers with 6+ months of experience who want to write production-grade code.
• Backend engineers transitioning from other languages (Java, Python, C++) to Go.
• Tech leads and architects designing high-load systems.
• Anyone preparing for technical interviews for Middle/Senior Go developer positions.

What will you learn?

• How to design systems that are resilient to failures and loads.
• How to avoid common pitfalls when working with goroutines and channels.
• How to write code that is easy to test and maintain.
• How to profile and optimize applications without losing readability.
• How to apply design patterns in the context of Go.

The book contains numerous code examples ready for use, as well as exercises to reinforce the material. After reading it, you will be able to confidently take on complex projects and write efficient, secure, and maintainable programs in Go.
