Svitlana Oliinyk

I am a Senior Mobile Developer specializing in React Native with over five years of JavaScript experience and four-plus years building production iOS and Android applications. I focus on end-to-end delivery, from requirements and architecture to testing and App Store / Google Play releases.

I design scalable mobile architecture and reusable component patterns that support long-term product growth, and I optimize app performance by improving rendering efficiency and reducing unnecessary re-renders across complex screens. I have implemented advanced analytics instrumentation using Mixpanel and established monitoring with Sentry and Firebase.

I have delivered subscription-based monetization flows using RevenueCat and Superwall and integrated services such as OneSignal, AppsFlyer, and Singular. I am experienced in CI/CD, Expo Updates, and contributing to stable production releases in both startup and established product environments.

I collaborate closely with product managers, backend engineers, designers, and founders to iterate rapidly and deliver high-impact features, with strong attention to architecture, security, and measurable user engagement.
