a software developer at JetBrains, working on coroutine support in the Kotlin compiler since 2017. Was responsible for stabilization and implementation of the coroutines design. Since then, he has moved to other features, namely inline classes. Currently, his work with coroutines is limited to bug fixing and optimization, since coroutines as a language feature is complete and stable and does not require much attention.
an Android developer at Avast. She started her career teaching Java classes at Prague City University, before moving on to mobile development, which inevitably led to Kotlin and her love thereof.
