  • Identify and resolve performance issues across the React Native layer, including JavaScript thread bottlenecks, render
  • optimization, and memory management.
  • Work with native modules and understand how React Native bridges to iOS and Android platform capabilities, including integrations with CGM hardware SDKs and Bluetooth data streams.
  • Participate in Lingo''s ongoing migration from React Native toward native iOS and Android where appropriate, contributing your perspective on what should migrate and how.
  • Conduct code reviews that raise the quality bar across the mobile team, sharing knowledge and holding a high standard for readability, testability, and maintainability.
