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.

Conference features

  • 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.

  • TechTalks

    Lots of technical content with a little bit of non-technical content. Our conferences help to find your way in the industry: you will know trends, tools, approaches, global updates of the languages and platforms.

  • 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.

  • Discussions

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


    Our support team will reply to you very soon and will not leave you alone.

  • 4K video

    So that you can see each character of the code in the IDE.


We would not be able to hold Joker on a regular basis without the tremendous support of our partners. Our conference is growing and evolving thanks to their efforts.
