Worked on the facebook/react-native repository to deliver structured previews for FormData and one-shot binary payloads in the React Native DevTools Network tab. The solution replaced generic placeholders with informative binary labels and multipart envelopes, ensuring that payload previews rendered accurately without modifying or draining request data. Leveraging Android development expertise and Kotlin, comprehensive unit tests were added in NetworkEventUtilTest.kt, with all tests passing and full manual validation performed in RN-Tester. The work improved debugging speed and reliability for network payloads, maintained alignment with DevTools expectations, and included thorough documentation and changelog updates to support ongoing collaboration and visibility.
