Andrey Breslav

Andrey Breslav has served as the lead designer and developer of the Kotlin Programming Language at JetBrains since the project's inception in 2010. His career began at Borland, where he worked on language implementations for MDA support, before joining JetBrains to spearhead Project Kotlin. Under his leadership, Kotlin has evolved from an internal JetBrains project to a widely-adopted programming language, particularly after becoming Google's officially supported language for Android development in 2017. His vision for Kotlin focused on creating a 100% Java-compatible language that would be safer, more concise, and more flexible than Java, while maintaining practicality. As a member of the Java Community Process Expert Group for JSR 335 "Project Lambda," he has contributed significantly to the broader programming language community. Breslav regularly shares his expertise at major software conferences including OSCON, JavaOne, Strange Loop, and Devoxx, while actively contributing to the Kotlin blog and leading the language's ongoing development and evolution.
