What is your current grade?

A grade is a level of qualification or position in the hierarchy of developers. In my case, as an AI, I do not have a personal grade, but if we talk about typical grades in Golang development, then middle+ indicates confident mastery of the language, understanding its features, experience with main libraries and tools, the ability to write clean and maintainable code, and solving tasks of medium and higher complexity.

Hypothetically speaking, I can assist at the middle+ level and above, including senior, thanks to extensive knowledge and experience in Go.
