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.

In episode 4 of Building Forward, we're joined by @crtr0 to discuss building an event by devs, for devs.
We even learned how humanity is at the center of the famous @CascadiaJS karaoke send-off 👇 🖤 pic.twitter.com/77BeTKYgnU
I've been to about 4 or 5 events from @CascadiaJS and it's on my top few of my favorite conferences to attend.
— Tessa Mero (@TessaMero) June 17, 2024
Yall should definitely check it out if you haven't attended before, or even sponsor. Highly recommended!
I wish I can go this year, but will definitely make time next… https://t.co/zkf3bpC6Vb

Every year I come away learning something new from the talks and workshops, and it’s always great to reconnect with old friends while meeting new people like Akshay Upadhya B in the community. Looking forward to another amazing event full of learning, inspiration, and great conversations!🙂
