I love working in developer education because I like code, words, and people. (And Python!)

As the Executive Editor of Real Python, I spend my time planning curricula, creating educational resources, building an exceptional team, and more.

When I’m not at my desk, I enjoy exploring the beautiful city of Vancouver on foot, laughing with my pub trivia team, and experimenting with seitan recipes.

Let’s level up our Python together!
