The company’s primary mobile application required specialized React Native expertise to support continued growth. Complex native integrations and platform migrations created technical challenges that its existing team lacked the experience to address independently.
Solution
Mobile Architecture Modernization
Toptal migrated the React Native application to Expo prebuild while preserving custom native modules and iOS Live Activity functionality, eliminating the need to maintain separate iOS and Android project folders.
Offline Functionality Development
The engineer built a custom Apollo Link supporting optimistic updates and offline caching, allowing the application to handle user interactions without continuous connectivity while also resolving bugs identified through Sentry.
Outcome
Simplified Application Maintenance
The completed Expo migration streamlined React Native upgrades and improved CI/CD processes, reducing the complexity of maintaining native platform code as the mobile application continued to evolve.
Improved Application Stability
The custom offline caching implementation strengthened the app’s ability to function without a network connection, while extensive bug fixes contributed to a more stable mobile experience.
