Worked on the surveyjs/survey-creator repository to enhance localization quality and stability, focusing specifically on Turkish UI text. Addressed a bug in the Dropdown Toolbox item by correcting the Turkish translation from 'Seçim Kıutusu' to 'Seçim Kutusu', aligning the interface with proper Turkish spelling and user experience standards. Utilized TypeScript and applied internationalization and localization best practices to ensure the change was precise, traceable, and low risk. The targeted fix improved clarity for Turkish-speaking users, reduced potential confusion in the toolbox, and contributed to a more consistent user experience across the survey-creator interface during the development period.
