Simon built huge portions of Flickr's back-end back in the day, and was almost single-handedly responsible for Flickr's internationalization, including all of that gnarly stuff related to moderation, abuse mitigation, and monetization. He built large parts of the Glitch social layer at Tiny Speck. Before all this, he was part of the Search team at Yahoo. He likes simple, scalable solutions to ugly, hairy problems. He is British, but we try not to hold that against him.
