Worked on the GIScience/sketch-map-tool repository to enhance Czech language localization, focusing on improving user experience for Czech-speaking users. Addressed a typo in the About section and expanded translations for Help section descriptions by updating the messages.po file, ensuring greater clarity and usability. Utilized localization and translation skills, specifically working with PO files and the gettext workflow, to maintain consistency and prepare the project for future multilingual support. The work did not involve new feature development or bug fixes beyond localization, but it contributed to reducing user confusion and support needs by refining the language quality within the application interface.
