Developer with a passion for testable, performant, and clean code

I love language design so I've been tracking the development of Kotlin since 2014 and using it since 2016. I absolutely love Kotlin. It's my go-to language for the JVM these days. It's super expressive yet concise with first-class support for properties, delegations, extensions, data classes, functional idioms, and now coroutines! I've worked on mixed Kotlin-Java codebases as well as pure Kotlin ones.
