I volunteered to judge at the DC STEM Fair.  There were significant delays throughout the day due to issues with their scoring software.  After the event I talked to the organizers and proposed a google sheet solution.  I set it up and ran scoring at the next fair. Organizers remarked that it was the smoothest the fair had ever run.  Following that success, I was asked back and ended up running the scoring for the DC STEM Fairs for a few years.
