Mark Percival worked as a mobile software engineer at Twitter where he focused on improving the mobile product for developing markets. He left Twitter to start with Ramy Adeeb in 2011 which was later acquired by Yahoo. At Yahoo he helped build the platform to move Yahoo's international sites to Tumblr.
