About Me

I'm a Senior Android Engineer with 8+ years of experience building secure, scalable mobile apps for banking and fintech.

I work in Kotlin and Kotlin Multiplatform, building high-performance Android apps and sharing code across platforms. Along the way I've built secure financial systems, integrated native components through the Android NDK, and designed mobile architectures that hold up in demanding production environments.

My focus is mobile security, performance and cross-platform architecture: the things that make financial apps reliable for the people who depend on them.

I approach engineering with discipline and curiosity. I like understanding how the pieces of a system fit together, and I keep refining both the code and the process behind it.
