Have you had experience mentoring or training junior colleagues?

Yes, I have experience mentoring and training junior colleagues. I usually helped them understand the basics of Go, explained idiomatic language constructs, design patterns, and best practices for writing clean and efficient code. For example, I conducted code reviews where I not only pointed out errors but also explained how to improve code readability and performance. I also organized small internal workshops on topics such as goroutines, channels, and working with context to accelerate their professional growth.
