I craft modern Android applications using the latest technologies. Always exploring new ways to build better, more performant native experiences.

About

I'm a passionate and results-driven Android Developer with expertise in building high-performance applications and SDKs. Skilled in Kotlin, Jetpack Compose, and Kotlin Multiplatform, with a strong focus on Clean Architecture and modern development practices.

Currently, I'm an Android Engineer at what3words. I contribute to the what3words Android app and build public and private UI component libraries that allow others to integrate what3words functionality into their own applications.

In my spare time, I'm usually playing chess, video games, hanging with my friends or exploring new technologies in native Android app development.
