What did attendees say?

"The partner workshops were interactive and well lead."

“I’ve been inspired through my conversations. Great experience and awesome people.”

"Our integration is now working beautifully. It scales to everything we need.”

“Hacking in person was an amazing experience, especially as a junior developer. It’s incredibly valuable to see first-hand how these brilliant minds approach problems, write code, and collaborate. You learn so much just by being around them!”

"It’s inspiring to connect with the people who use, contribute to, and support the project. It gave me a deeper appreciation of the impact we’re making together."

“Well organised tours and team building activities. All over very nice and memorable experience!”
