Like most startups, at the beginning of its journey Faire was looking for an efficient solution to base its tech stack on. Here is their story of starting with Java and migrating to Kotlin in a year.

DoorDash uses Kotlin for all their backend services and infrastructure. Hundreds of engineers work with Kotlin across a massive system spanning multiple repos. Two years ago, they made the bold move to split their existing legacy Python monolith into multiple backend services, which they developed in Kotlin. This upgrade resulted in tremendous improvements: Better software performance. Сleaner code. Easier code reviews. Another great thing about Kotlin is that people coming from Java, Golang, and Python find it really easy to get started. Kotlin is an excellent choice for server-side appl

Kotlin is becoming a language of choice for server-side application development. Null safety, 100% Java interoperability, coroutines, and many other features make Kotlin ideal for backend programming. We’re launching a series of webinars to help you to learn more about backend development with Kotlin or even try it for the first time. In the next few weeks, speakers from JetBrains, Google, and Confluent will cover three essential topics of backend development: event stream management with Kafka, running applications in the cloud, and backends with Spring Boot. Kotlin and Apache Kafka The

The Kotlin 1.4 Online Event materials are available for you to watch any time. Recordings of the talks, and Q&As are available on the event web page, along with slides. You can watch the recordings in order using the Kotlin 1.4 Online Event playlist Kotlin 1.4 talks At the time of writing, the recordings from the Kotlin 1.4 playlist have been viewed more than 120 thousand times in total.

TL;DR From now on, we will release Kotlin 1.X every six months. These releases will be date-driven, not feature-driven. The Kotlin IDE plugin will be released simultaneously with Kotlin, and on top of that — every time IntelliJ IDEA is released. Major IDE features will arrive in releases synchronized with IntelliJ IDEA. Why the new cadence? Since Kotlin 1.0 came out in 2016, we’ve built our release schedule around new key features in the language. This meant that until big language features were ready we would not release anything at all. As a consequence, we delivered changes and improveme

You can read this blog post in other languages: The new edition of Kotlin Census is here! By the end of 2019, more than 4 million people had used Kotlin. This is a great number of people, and of course, they have a great number of use cases behind them. We care deeply about making sure Kotlin delivers a great experience for everyone who uses it. We want to improve it to help everyone in the community bring their ideas to life with Kotlin. This is why your feedback is so important to us. Please share with the Kotlin team how you’ve used the language over the last year. What did you like abo

It’s turning into a nice tradition to broadcast KotlinConf. This year the community will have full access to the conference via the KotlinConf 2019 Live broadcast. We will be covering four of the presentation tracks scheduled for the conference, and the icing on the cake is that there will be some special content that’s only available online through KotlinConf 2019 Live! Tune in to watch 12 insightful interviews with the speakers over both conference days, moderated by Huyen Tue Dao, also a speaker at KotlinConf and the host of "Android Dialogs". We will begin our broadcast with the Keynote

2019 has been amazing for the Kotlin community with developments like the language of choice on Android, a wave of Kotlin/Everywhere events, Breakout Project of the Year at OSCON ’19… and the year is not over yet. Today we reveal one more wonderful opportunity for Kotlin lovers: get together for KotlinConf 2019 Global with your local user group! Organize a meetup for your community to watch the KotlinConf 2019 keynote and other sessions together, and JetBrains will support your community. If you’re not an organizer, keep an eye on future blog posts and follow @kotlinconf on Twitter, where

When we say ‘Kotlin is everywhere’, we mean it. Kotlin works on all platforms, and it allows you to develop all types of applications. Developers are excited about Kotlin and hungry for opportunities to learn more. Now it’s time to bring it to your city with the support of JetBrains and Google. We’re happy to announce our new program, Kotlin/Everywhere – a series of community-driven events focusing on the potential of Kotlin on all platforms. Its goal is to help people learn the essentials and best practices of using Kotlin everywhere, be it for Android, iOS, back-end, or front-end. Join t
