Worked on the clerk/javascript repository to standardize HTTP request headers across mobile platforms by introducing the x-expo-sdk-version header in Clerk JS. This feature aligned mobile HTTP requests with established iOS and Android SDK patterns, supporting more reliable server-side analytics and feature flag interoperability. The implementation involved API integration and mobile development using React Native and TypeScript, with careful attention to commit traceability and cross-platform consistency. By focusing on HTTP header management and Expo SDK versioning, the work established a foundation for improved server-side correlation and future SDK ecosystem alignment, addressing compatibility and consistency requirements without introducing major bug fixes during the period.
