During June 2025, Continue Jump contributed to the team-mirai-volunteer/action-board repository by implementing a feature focused on branding consistency and user experience. They replaced the term ボランティア with サポーター throughout the user interface and in SQL migration scripts, ensuring unified terminology in both frontend displays and backend mission descriptions. This work required careful coordination between TypeScript-based frontend components and SQL database management, aligning data and presentation layers. By centralizing terminology, Continue Jump laid the groundwork for easier future localization and improved maintainability. The depth of the change demonstrated attention to detail in both user-facing text and underlying data structures.
