Erin Dees

Hi! I’m an engineer, author, and coach living in the Pacific Northwest.


I learn, I do, and then I teach

Well, hello there! I'm Erin, a programmer, author, and coach living in the Pacific Northwest. (You may know me by a different first name, but I've been answering to “Erin” since 2017.)

One of my favorite things to do—whether the activity is programming, cooking, board games, or race walking—is to immerse myself in a skill and then share what I've learned.

For something technical like software testing, this means writing books such as Effective Testing With RSpec 3. For physical skills like race walking, it means coaching teams of athletes.


It’s an essential resource for Rubyists looking to learn RSpec, or for those who use it every day. I’ve already started using it regularly as a resource.

Definitely a book I would recommend to others wanting to expand their programming horizons.
