Ever wondered what the job of CTO encompasses? This article does a good job at it. It's especially nice that it's split based on company size. Indeed, the role can change dramatically depending on how big an organization is.

I'd take the more stack related side of this article with a pinch of salt. It seems a bit too specific to the company behind the story. The rest of the article rings true and spot on though.

Interesting insights about the minutiae of the CTO role.
