Hi! I’m Cassidy, and I like to make memes and dreams and software. I’m the Senior Director of Developer Advocacy at GitHub! Outside of that fancy title, I’m a startup advisor and investor, open source-er, and meme-maker on the internet. I enjoy building mechanical keyboards, playing music, hanging out with my family and friends, and teaching in my free time.

It’s Blogvent, day 21, where I blog daily in December! I saw a post on Mastodon recently: We need to normalize declaring software as finished. Not everything needs continuous updates to function. In fact, a minority of software needs...
It’s Blogvent, day 20, where I blog daily in December! Last year, almost exactly a year ago today, I wrote that I was becoming a minor writing utensil snob. Unfortunately for my wallet, I don’t think I can call myself a minor snob...
