About conference

Joker is a conference for Java developers that’s held since 2013. It’s one of two largest and oldest Java conferences in Russia (the other is its «twin», the JPoint conference). It is the right place to go both for practical talks (say, about using Spring Boot) and getting to know JVM under the hood. The conference is held by JUG Ru Group.

    You may chat with speakers and experts right after the talk. Both online and offline.

  • Change of scene

    Offline is back. This is a chance to change the scene, listen to live talks, chat with your colleagues, and just enjoy your time at the afterparty offline.

  • TechTalks

    There is lots of technical content with a little bit of non-technical content. Our conferences will help you find your way in the industry by teaching you about trends, tools, approaches, and global language and platform updates.

  • The content selected by the experts

    The content is included in the program only after it has been checked by the program committee, which has experts with wide experience in Java development.
