Worked on enhancing fuzz testing and memory management for the google/libphonenumber repository, focusing on improving reliability and security. Delivered targeted fuzz testing enhancements by adding new fuzz targets for components such as AsYouTypeFormatter and PhoneNumberUtil, which expanded coverage and improved detection of edge-case bugs. Addressed a memory leak in the fuzzing workflow by replacing raw pointer management with std::unique_ptr, ensuring safer and more efficient memory handling in C++. Integrated these fuzz targets into the OSS-Fuzz build system using Shell and C++, streamlining continuous integration and enabling more robust, automated software testing across multiple components of the library.
