You’re welcome to submit any Kotlin-related talk that you think will be interesting for the attendees. Here are some topics that we expect will engage their attention:

Server side, web, desktop, mobile, IoT, scripting, data science, frameworks and libraries, functional programming, concurrent programming, case studies, coroutines, meta-programming, and deeper language features.

When it comes to platforms, we would really like a good mix of everything, including the JVM, Android, JavaScript, and Native. Multiplatform apps you’ve put into production or useful libraries make for good topics, as well.

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, of course.

Abstract – Keep it concise and to the point, aiming for 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, 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.

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 only cover travel and accommodation for full sessions but not for lightning talks.

Please make sure you read and agree to abide by the Code of Conduct prior to submitting.
