Worked on the facebook/react-native repository to deliver a targeted fix for Android WebSocket authentication, addressing an issue where caller-supplied Cookie headers were not preserved during WebSocket upgrades. Using Kotlin and Android development skills, the solution maintained shared OkHttpClient behavior, including connection pooling and dispatching, while disabling per-request cookies specifically for WebSocket transport. The fix ensured that cookies continued to be forwarded via the CookieJar as needed, restoring authenticated real-time streaming for Android applications and achieving parity with iOS behavior. Validation included server-side logging and production app testing, and the changes were merged following thorough code review.
