Worked on the WebKit repository to enhance the stability and correctness of ResourceRequestSoup in response to evolving privacy requirements. Addressed a runtime issue by updating the code to access vector data through the private span() interface after vector.data() was made private, ensuring continued reliability in resource request handling. This targeted fix maintained performance and privacy guarantees by preventing unnecessary data exposure and copies. The work demonstrated careful alignment with updated APIs and clear traceability through a single, well-documented commit. Utilized C++ and the C++ Standard Library, applying low-level programming and memory management skills to preserve code quality and maintainability.
