Jamstack Conf 2021

I arrived in San Francisco on Monday to prepare for Jamstack Conf. The plan was for the MCs and keynote to be all done in person, while the rest of the event was virtual!

We had rented out a house and hired a production company to do all of the sets and filming, and it was very exciting. It was early 90s-themed, and we had been getting so hyped as we got closer and closer to the start.

Tuesday was a full day of rehearsals and blocking out how timing would go, as well as some filming. And then, our prop van was stolen! A bunch of our things we were going to use were gone (luckily they found the van later), so that all had to be re-planned out. The next morning, Wednesday, the day of the event, we had a super early morning call time… and a bird ran into the transformer and blew out power to the entire area. It was a PANIC trying to plan what would happen next, with no power or WiFi in our perfectly planned set.

We ultimately had to cancel one of the three tracks at the conference, had Phil in the UK host the start of the event, we powered the house with a truck (literally), and one of our organizers had to produce the event at a nearby hotel while we tethered as much as we could from our phones. We were heartbroken that we didn’t get to show all that we wanted, but are so happy with the results anyway. You can check out the videos now, and more will be coming soon of the clips we were able to film offline!
