We consider applications according to the following guidelines:
  • The topic's relevance: you are going to discuss things that participants of the conference find useful not only yesterday but today and in the future. In addition, the topic of your session corresponds to the theme of the conference, and the content matches the stated topic.
  • Your session dives deep into the details of the stated topic: there is no need to talk about yet another Hello World (unless you think it's a new, not widely known, but very promising technology).
  • Originality — there is technical novelty in your session; the content either hasn't been published before or presents a well-known topic / problem in a different light.
  • Practical applicability — the content is important from a practical point of view, you not only cover the existing problems / solutions, but also share your experience.
  • Speaker's expertise and publicity.

In order to submit your application, please, fill in the form below. If you feel like you need help to prepare your session you can count on us: we can appoint a personal curator who will review your material and organize repetitions.

We expect your session applications of 60 minutes excluding answers to questions. But we also consider materials for 2 slots and more.

Usually, we contact applicants within a week after the submission. If that hasn't happened feel free to contact us via email program@jokerconf.com.

Please don't forget to read the speaker's memo.

If you are representing a speaker, please fill the form using the speaker's contact information. You can leave your contacts in the field for the reply to the last question about a co-speaker.



Joker 2021 conference will be held online.

We run broadcasts from our studio in Saint-Petersburg where we have a large production team and all the equipment. If you want, you can come to the studio and hold your session there.

Please pick a preferred format: *

We want to make the conference interesting and fun so we are open to experimental session formats proposals. Don't hesitate to offer your ideas below!

Please pick the kind of your session: *

The title should be clear and reflect the essence of the session. Remember: brevity is the soul of wit.
Please share enough details to make the point clear. Describe technologies you will use, represented problems and solutions, and the audience takeaway.
The session must be focused on using a technology, not on its advertising.
What and in what order you will talk about, in bullets.

After several online conferences, we noticed that sessions with two or three speakers turn out to be more interesting for attendees. If you have someone to invite as a co-speaker, we recommend considering this option.
