How do you rate yourself on a grade?

Assessing myself as a Middle Golang developer, I can say that:

• I confidently write clean and maintainable code in Go.
• I know the main patterns and idioms of the language.
• I have experience working with goroutines and channels to implement concurrency.
• I understand the principles of working with network protocols and REST API.
• I can work with databases and use ORM or drivers.
• I am familiar with testing and profiling tools.

At the same time, I continue to develop, learn new language features and best practices to grow to a Senior level.
