About Me

From architecture to
App Store.

I'm a Senior Mobile App Developer with over 4 years of hands-on experience crafting high-performance, cross-platform mobile applications. I specialize in React Native and native iOS (Swift) development, building everything from gamified LMS platforms to large-scale religious apps reaching 2.1M+ downloads.

My work spans the full mobile lifecycle — architecture design, feature implementation, App Store/Play Store deployments, and crash-rate optimization. I thrive in cross-functional teams, collaborating tightly with backend and design to ship stable, scalable releases.
