Talk #1: Kotlin from backend developer perspective

by Bartłomiej Szczepanik

8 months ago my team decided to select Kotlin as our language of choice for our backend services. Since then we write new code only in Kotlin and slowly migrate our existing codebase. I'd like to share experiences we gathered so far: good and bad parts of the migration, gotchas and Java/Kotlin compatibility issues.

by Paweł Marks

For many years spring frameworks has dominated web development in jvm environment. Later, rise of adoption of microservice architecture resulted in popularity of the new generation of web frameworks, that are lightweight, easy to configure, understand and debug. Theese now frameworks are now used not only for microservices but for anything related to broadly defined web development.
Ktor is one of theese frameworks. It is lightweight, fast and easy to understand. Most importantly, it is developed by the creators of Kotlin. So let me be your guide in the world of idiomatic Kotlin web development.
