If you have a cool idea on a topic that is not on the list we will be happy to consider your application anyway!

Submission process

Each submitted talk will be examined by at least three reviewers from the Program Committee.

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.
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..



We are going to run a hybrid conference this season: some talks will go live online, some will be held offline.

Please pick a preferred format: *

We don't know what the COVID restrictions will be at the moment of the conference so there's still a risk of changing the conference format to online.

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 found out that sessions with two or three speakers are way more attractive for attendees. If you have someone to invite as a co-speaker please consider it.
