The hacker was spotted competing in a hackathon at Backplane, a startup funded by Lady Gaga.
During the hackathon, I got to work with him as he built an app that allows you to see where your Facebook friends are on a map. Aviv Ovadya, a Quora engineer, was also on the team.

His entry didn't win, it lost out to a group of high school students.
