• 15+ years of software engineering experience, with deep expertise in native mobile engineering (Swift, Kotlin, Android SDK, iOS frameworks, ReactNative).

• Proven track record of architecting and delivering mobile applications at scale, including complex, distributed consumer systems.

• Experience shaping cross-platform strategies (React Native, Kotlin Multiplatform, or similar) a strong plus.
