Nayden Gochev

The Bulgarian Java User group was founded in September 2007 along with a mailing list for discussion
of any Java-related questions, problems and upcoming technologies. After a short period of dormancy,
five members set leadership board in 2013. It triggered regular meetups and sessions once or twice a
month with local and foreign speakers. The JUG first took part in several Adopt OpenJDK activities and
soon after that became JCP member. The events and workshops organized by the community are
sponsored and backed up by IT companies on the Bulgarian market
