Senior Data/ Site Reliability Engineer Wikimedia Foundation (Wikipedia)

Avishua is a senior data person based in Brooklyn, NY. When he isn't setting up data infra or sneering at poor data viz, you can find him going to concerts, trying new vegan spots, playing games, diving into Wikipedia rabbit holes, philosophizing, or most likely- cuddling with his cats.
