Cristian Garcia

Cristian Garcia

Cristian fell into Gradle when it was first adopted by Android. Being the Android lead for a big marketplace Cristian learned quickly that Gradle was an essential tool to optimize builds. He enjoyed that if this tool was well-used it can keep complexity far from the developers and provided a nice DSL for customization. Cristian authored the simple-flank Gradle plugin (flank Gradle plugin focused on making UI Tests cacheable). Now, working at JetBrains, he is trying to make reproducible fast builds in a big Kotlin Multiplatform project. He enjoys exploring nature with his family in the countryside of Barcelona.
