Chenwei Choo focused on security hardening for the LifeSG/web-frontend-engine repository by addressing a vulnerability identified during a VAPT assessment. He upgraded the Axios dependency to version 1.7.9 using JavaScript, ensuring that the application’s risk exposure was reduced without introducing any changes to existing features or user experience. His work demonstrated strong skills in dependency management and security patching, maintaining compliance readiness while preserving application stability. By applying a targeted patch rather than broad code changes, Chenwei ensured the frontend codebase remained robust and secure, reflecting a careful and methodical approach to software maintenance and secure release practices.
