For 10 years, Scala Days brings together developers, researchers, and companies to share their experiences and new ideas around creating applications with Scala and related technologies, like Spark, Kafka, and Akka. Scala Days provides a unique opportunity for Scala users to interact with the contributors to the language and related technologies and connect with fellow developers.

The organizers invite experts in the field of Scala and its applications in business, academia, and the broader community to submit presentations by January 17, 2020.

The conference aims to provide up-to-date and practical knowledge on Scala for software developers, software architects, team leads, and researchers.

Scala Days seeks to provide topics relevant to developers using Scala in various businesses. You’ll find some examples below. While planning a talk, you should consider which aspects of your topic are most relevant to your audience. Please take into account that the knowledge of your audience varies.
