We worked on three projects for Russian IT giant Mail.ru Group. First one is 'Buy a car' application for the most popular car search in the Runet — '[email protected]'. It allows to be up on news of car industry and helps to sell or change a car. Second onr is the News feed app. And the third one is Mail client that gives you access to all features of your mailbox via POP/SMTP, web- and wap-interface. Today this app has over 27 million users what makes it one of the most popular post services.
