KotlinConf is the official Kotlin Community conference by JetBrains.
It is devoted to the Kotlin programming language and was founded in 2017 to provide a place for our wonderful community to meet, learn and share their ideas, skills, experience and success stories.
This time, we’ll be gathering in Krakow, Poland, on April 21–23 2027, bringing 2,000+ Kotlin engineers together to learn and share skills in a day of workshops on April 21, and at the conference itself on the 22-23 April.
Share your Kotlin story!
Whether it's about finding innovative ways to use Kotlin, challenges you've faced, a framework you've created, or anything you feel could help others on their Kotlin journey, we’d love to see your talk proposal!
Need inspiration?
Check out our CfP pages on KotlinConf.com.
Submit your proposal by 27.11 and help other engineering teams learn from what you built, how you built it and what you discovered along the way.
About your talk
We receive many submissions and only have a limited number of slots. Please consider the following tips when submitting your talks.
Title – We review each talk in its entirety, but there’s no denying that a catchy title is a plus. At the same time, make sure that the title is accurate and consistent with your abstract and the content of your talk.
Abstract – Keep it concise and to the point, roughly 200 to 400 words. Make sure that your abstract accurately describes what you’ll be covering in your talk and what the key takeaways will be for the audience.
If you’re going to discuss a popular topic, try to find an angle that distinguishes your talk from others. For instance, using Kotlin with Spring might be a popular topic, so it’s important for us to understand how your specific approach is unique.
While this applies to all talks, it is even more relevant for case studies, which is also a crowded field. If you’d like to present a case study, make sure to highlight its key aspects in your abstract and try to include specific numbers and metrics in your talk.
Level – Try to accurately define the level of your talk. Keep in mind that if your talk focuses on the language itself, it will be more likely to interest most attendees if it is not intro-level.
Theme – If multiple themes are relevant to your submission, please select up to two themes that best represent its main focus.
Session length – Full sessions are 45 minutes long, including a Q&A session (which is optional). Lightning talks are 15 minutes long. Please note that we cover travel and accommodation for full sessions but not for lightning talks.
