Learning how to write easy to read and understand code is essencial. It improves both your and your teammates performance.
Use real world examples
Internet is full of theory. The same comes with books. From me, you'll get projects or examples from real world examples (very often from my own projects). No more only theory. Practice is the key!
Get premium materials (videos etc)
Only subscribers will receive special materials that will help understand the key concepts of Go (and software engineering in general).
Have the impact of what I prepare for you
I listen to my subscribers. You can suggest a topic. I'll put it very high on my to-do list! This is how OAuth2 and Go was created!
That's not all! I have a several open-source projects like GoBDD or cyclop but most of my time I focus on my blog developer20.com where I share my knowlage with others.
