Worked on enhancing the security and stability of the pangeacyber/pangea-javascript repository by upgrading core frontend dependencies. Focused on updating React and React-DOM to version 19.2.1, this effort aimed to mitigate known security vulnerabilities and ensure compatibility with the evolving JavaScript ecosystem. The work was delivered through a single, security-focused commit with clear messaging to support traceability and facilitate future audits. Demonstrated skills in React, JavaScript, and frontend development, with an emphasis on precise dependency management and repository hygiene. The approach minimized risk by limiting changes to essential areas, supporting smoother future maintenance and improved end-user security.
