CFP Description


Dear speaker, our conference will take place in Lviv, Ukraine. Lviv is located on the west of Ukraine and is of one of the most famous tourist destinations in the region. If it’s your first time in Lviv, you will love it.

Thank you for your interest in participating in JavaDay Lviv! We will do our best to review your submission and get back to you asap.

Here’s more about our talk formats and other helpful information.

Online Talk

This type of talk is not a typical online format where the speaker gives a talk through the call and doesn’t have any feedback. We call it “Advanced Online” talk, and it means that we will have the next setup: - Speaker gives a talk trough the call and on this call, the speaker sees the Event moderator and Audience that will be health on a single location by one of our partners “CoffeeJUG”. It means that the speaker will have a feeling of a real audience. - After the talk out moderator will allow people who watched this talk online - ask questions using their mic and the speaker will be able to answer the question directly. Also, offline listeners on CoffeeJUG will have another moderator who will allow people from the audience to ask questions directly and receive answers.

Offline Talk

This type of event will be held in compliance with the requirements of martial law, taking into account the situation in Ukraine. Considering this, we will conduct an offline event with a limited number of participants, 2 streams, and only 10 speakers. This is an initial agreement and we hope that if it will be changed then only into the positive side.


Lviv, also, is a capital of Ukrainian IT industry. We proud of it. On this event we expect to have about 250-300 participants who mostly work with Java technologies and JVM-based eco-system.

Level of our participants will be different. So please, add more information about your talk complexity (for all, for beginner, for intermediate or for experts).


We would be a super happy to see your submission in scope of one of the next topics :

  • Architecture & Security
  • JVM Languages
  • Machine Learning & AI
  • Cloud, Containers & Infrastructure
  • Server Side
  • Big Data & Data Mining
