It’s got everything — a dedicated fan base of 10+ years, close family vibes, long held traditions (the best karaoke!), sublime locale, and a flair for the atypical/creative conf sessions.
Def apply + attend! https://t.co/yqrEbh0icL
The reason why @CascadiaJS is one of my favorite conferences is because you can truly feel the passion and care that everyone puts into it. There's a real sense of community, it's amazing 🙌👏💜

Once again, @CascadiaJS did not disappoint—I love that we have a community-focused conference right in the PNW. It's always inspiring to hear about what people are making, stretch my perspective, and meet new friends.
