Leading programmers of INSOLLO entertainment took part in the Kiev programmer convention DOU Hakaton. The goal of this event is to create a working application and demonstrate it to the other participants. The application can be created both alone and as a team, in any language and for any platform: the main point is the result. Hakaton is the first Kiev association of programmers created to share experience in a relaxed and friendly atmosphere. The co-organizer of Hatakon and sponsor of presents - certificates from Amazon - was INSOLLO entertainment.
