Worked on the facebook/react-native repository to enhance cross-platform networking reliability by implementing Base64 encoding for binary response bodies within the C++ NetworkingModule. This update addressed data corruption issues when transferring binary data to JavaScript, aligning the C++ module’s behavior with existing Android and iOS implementations. The solution localized encoding logic in a private helper, ensuring the public API surface remained unchanged. Comprehensive unit tests were added to validate the correctness of the new encoding path and to confirm that non-binary responses were unaffected. The work demonstrated proficiency in C++ development, JavaScript integration, and rigorous unit testing practices.
