Drive operational excellence including crash analytics and debugging across platforms.

5+ years building mobile applications, with at least 3+ years focused on **React Native application development.**
Deep understanding of React Native internals: bridge architecture, native module lifecycle, threading, and performance optimization.
Proven experience building **native modules and ViewManagers** for React Native (both iOS and Android).
Strong **TypeScript** skills with experience publishing and maintaining npm packages.
Working knowledge of **Swift** for iOS native bridge development.

Experience debugging complex issues across different React Native versions and app configurations (Expo, bare workflow, monorepos).

Strong communication skills for working directly with external engineering teams during integrations.
Quality mindset: **Jest**, **@testing-library/react-native**, automation, and observability best practices.
