What I'm looking for

I seek senior mobile engineering roles where I can architect scalable SDKs or lead teams, focusing on performance, offline-first systems, and cross-platform/graphics-driven products.

I am a Senior Android Engineer and Technical Lead with 9+ years building scalable mobile architectures, proprietary SDKs, and high-performance graphics systems. I have led engineering teams, driven technical due diligence for M&A, and standardized platforms across large app portfolios.

At my current role I architected a unified internal SDK deployed to 900+ apps, standardized IAP, ad mediation and remote config, and managed Android teams to modernize legacy codebases. Previously I built 0-to-1 mobile products, integrated on-device ML with TensorFlow Lite, and developed custom OpenGL shaders for real-time image processing.

I pursue complex engineering challenges across mobile, game development, and cross-platform systems, delivering robust offline-first architectures, performant rendering, and reliable synchronization. I bring hands-on expertise in Kotlin, Java, C#, Jetpack Compose, and graphics programming to drive product quality and technical scalability.
