Kotlin Dev Day
Kotlin Dev Day is THE in-person conference for anyone passionate about Kotlin — and you could be part of its next edition at Circa Amsterdam.
Take the stage in front of hundreds of fellow Kotlin enthusiasts at Amsterdam’s first fully circular venue.
We welcome your session proposals across a variety of Kotlin-related topics. The 2025 edition will carry a touch of AI, so consider incorporating this exciting frontier into your talk.
Get The Full Conference Experience
All speakers will receive our exclusive speaker swag! You'll also be invited to the speakers dinner on the night before where you'll be having fun with the others. A great experience and an opportunity to expand your network and make new friends (that also like Kotlin).
A Not-for-Profit Conference!
Lastly, we want to emphasize that this is a Not-for-Profit Conference. This means that all profits will be flowing back to the community.
The attendees are in control of where the money goes. We'll give them options to choose from. It will be something related to the community or software development in general.
Feel free to make a suggestion!
We're looking forward to your submission.
Kotlin Dev Day is proudly powered by Xebia and Co-organized with Flock.

Kotlin is up and coming and we're riding the hype train! The last Kotlin Dev Day was a huge success and welcomed over 600 delegates.
On November 27th, the third edition will take place in Amsterdam and you can be a part of that. Join JetBrains experts and other Kotlin enthusiasts on-stage!
We are open to basically everything, no matter whether it’s about the language, backend, Android/KMM or native, Kotlin libraries and frameworks, war stories or real-life experiences. The 2025 edition will carry a touch of AI, so consider incorporating this exciting frontier into your talk.
The rating of the talk is based on:
- Its link to Kotlin
- Difficulty level
- Demo is a plus
- Live coding is a plus
- No marketing of products and tools
Use the fields in the submission form to take us through your talk. This CFP will close on July 31st 2025.
After the CFP closed, our committee will rate all the submissions and put together the best program. All submissions will go through the selection process. As we expect we will need to handle a lot of submissions, so we can not guarantee your talk to be accepted.
Good luck and we look forward to your submission!
