The author is actually a fairly junior developer (graduated in 2013), but I must hand it to them for taking the initiative of getting published by such a large entity (oreilly media) and locking down speaking engagements (GopherCon) so early in their career!
They have a bright future even if this article does not contain the most accurate advice.
Meh. I don't want to take it away from the author, it certainly shows they're motivated, but I have a hard time this isn't a textbook example of how publishers/conference organisers are trying hard to get "underrepresented" token demographics in cover. Even if it is to perform trivial talks (a glorified "intro to channels in golang"... really!?) or write platitudes like said article. They're clearly underqualified to distillate advice to anyone, maybe interns/students could benefit from this though.
