How do you rate yourself in terms of level — middle, senior?

Assessing myself as a middle Golang developer, I possess confident knowledge of the language and standard library, can write clean, maintainable code, and work with the main tools of the ecosystem (e.g., go modules, go fmt, go test). I have experience working with goroutines and channels to organize concurrency, understand basic design patterns, and can debug applications. At the same time, I continue to develop in the areas of architecture, performance optimization, and more complex aspects of the language to reach a senior level.
