About

I specialize in building high-performance mobile and multiplatform applications. Over the last decade, I've worked across Android, iOS, Kotlin Multiplatform and native C++ systems, helping teams solve difficult technical challenges involving performance, interoperability and scalability. More recently, I focus on AI-powered applications and on-device LLM integrations through open-source projects such as Llamatik.
