How long have you been programming in Go from a professional experience perspective?

Commercial experience with Go usually begins with initial projects where the language is used for developing server-side logic, microservices, or CLI tools. For example, I have worked with Go for over 3 years, creating high-load services using the standard library, goroutines, and channels for concurrent programming. In real projects, Go was used for building REST APIs, processing message queues, and integrating with databases.
