Kotlin™ Dev Day


Important note
We’d like to announce that we unfortunately need to postpone Kotlin Dev Day which was planned for the 16th November 2023.

In order to run Kotlin Dev Day to the highest standards we need the support of sponsors, but with current downturn in the tech industry it has proven difficult to find these important partners.

We are still heavily invested in the Kotlin community and will continue to organize smaller events in the upcoming months. Let’s hope the outlook in 2024 is better and we can continue to bring this conference to you and the awesome Kotlin community as a whole.
