Focused on backend development and frontend stability, implemented robust token refresh automation, refactored HTML parsing logic, and modernized JavaScript and SCSS assets. Addressed security by hardening authentication flows and external link handling, while also updating dependencies and synchronizing theme subthemes for platform alignment. Used PHP, JavaScript, and Drupal theming to streamline code quality, reduce technical debt, and ensure maintainable, reliable feature delivery across authentication, search, and decision announcement workflows.
