📢 Call for use cases!📢 Do you use Kotlin for professional server-side development? We're looking for participants for a short use-case interview. If you're interested, please reply to this tweet and we'll get in touch with you.

@kotlin Coinverse's newsfeed is generated using @kotlin on the server-side. A Jar deployed to @googlecloud creates and saves the content to @Firebase Firestore that the app can consume. I'm looking forward to refactoring with Cloud Functions now that it's avail! play.google.com/store/apps/det…

@kotlin We have built a bank with Kotlin server-side (memo.bank/en/posts/hello…). I would be interested by discussing our use cases with you.

@kotlin Khipster.dev 😁

@kotlin Hi, we used Kotlin for all our JVM backend applications (~20). Using @springboot , @arrow_kt, graphql-kotlin, Mockk and since this week Kotest.

@kotlin Several of our backend teams in Adobe are using it for Server Side development (API development, high throughout realtime services, tooling, etc)

@kotlin @devexperts started using #kotlin as a substitute for Lombok plugin to reduce the boilerplate of our Java code. Then we progressed with Kotlin for backend development, primarily for Spring-based services + mockK for testing

@kotlin Of course, we aka Vert.x users use #Kotlin a lot

@kotlin Made bunch of backend services in Kotlin, the most used one is internal distributed buildcache service (Buck, Bazel, Gradle cache) Serves up to 30k requests per second with p99 latency of ~ 1ms

@kotlin a lot of nature.com runs on #http4k. It is in the top 1500 popular sites on the web (according to alexa). we also built a neobank with it.

@kotlin I started out with mixed Java/Kotlin code and then switched to pure Kotlin using Spring Boot for microservices.

@kotlin I use it with vertx. Here’s my YouTube that shows some examples. youtube.com/channel/UCsTeW…

@kotlin Using Ktor, and also Vert.x

@kotlin Micronaut + Kotlin @wearemakery

@kotlin @s_anastasov We use Kotlin with @http4k for a project for the Dutch government

@kotlin In ONAP, a Linux Foundation project, we built a model driven (TOSCA-based) serverless platform coupled with workflow engine supporting execution of kotlin scripts, Java and python. Uses a streaming gRPC-based communication. See arch: bit.ly/3dG28He

@kotlin What? I thought everybody used @kotlin for server side development? Are there any other languages worthwhile? Maybe Java will reach feature parity in version twenty-something @venosov

@kotlin Yes, we do at @StackHawk

@kotlin We at Mercado Shops @MercadoShops (BU within @Mercadolibre) use Kotlin + Spark Framework to develop our backend services with a direct impact to thousands of sellers and buyers 👨‍💻

@kotlin #Kotlin #Vertx #grpc

@kotlin I'm using @kotlin with @vertx_project for a major bank's in house distributed tracing solution

@kotlin Yes, we use Kotlin with Spring. We also use Kotlin + Spring + GraphQL. ubie.life/Top_EN

@kotlin @alpasdev kotlin web-framework and built @getcleaver! 🔥🚀

@kotlin Yes, I used server-side Kotlin when developed mobile game "SEVEN's CODE" and in combination Spring Boot and gRPC. Also I wrote selveral magazine articles and spoken at conferences in Japan about server-side Kotlin. youtube.com/watch?v=pv01J0…

@kotlin Hi ... we use #quarkus and #kotlin for several backend projects...

@kotlin Over a year ago at @Affirm we decided to introduce an alternative language to Python to our backend. We were looking for a typed modern language and after several weeks of discussion we decided on Kotlin. We have now multiple teams working with Kotlin and we couldn't be happier

@kotlin I’m interested :)

@kotlin We use Kotlin heavily within my team at Liberty Mutual for both in both containerized and serverless (AWS Lambda) workloads.

@kotlin I use @arrow_kt ( ͡° ͜ʖ ͡°)

@kotlin We use it with #vertx for ETL processing and with #spring for building APIs. There are so many awesome use-cases for Kotlin syntactic sugar in legacy #telecom stacks. You can find good amount of examples here: github.com/sip3io

@kotlin @antonarhipov At @4sh_france we use Kotlin in several projects, ranging from backend deployed on azure for globally distributed business critical mobile application to smaller usages in the retail, silver economy, transport or project management industry. Mostly with http4k or spring boot

@kotlin Qovery is using Kotlin for server-side deployment. Our control plane is 100% Kotlin. Contact us hello @ qovery.com

@kotlin We use Kotlin with @springboot and @micronautfw

@kotlin Yes we are using Kotlin and super happy with it :-)

@kotlin I used Kotlin for a lot of use cases throughout the years, from writing an automated test framework to e-learning applications and more. Recently I've been working on e-learning material that targets the security aspects of servers using Ktor and Exposed.

@kotlin Yes, with Spring Boot mostly. Payments space.

@kotlin @abreslav I do, with Micronaut
