Mobile apps, built and shipped.

I’m Donald Amoke, a mobile engineer in Abuja. I build React Native apps with native Kotlin and Swift where they need it, take them through the App Store and Google Play, wire up how they make money, and keep them running after launch.

About

I work best owning an app end to end: the architecture, the native code, the release, and the unglamorous months after it. Most of my work is client apps that have to earn money, so subscriptions, ads and payments are things I test with real purchases, not things I hand off.

I studied computer science at the University of Nigeria, Nsukka. I also build with AI coding agents deliberately, steering them through native features to a production standard, and I’m open to contract work and full-time remote roles.
