Worked on enhancing localization and accessibility for open source projects, focusing on Greek language support. In the FreeTubeApp/FreeTube repository, addressed gaps in Greek translations for SponsorBlock Settings and AGPLv3 by updating XML and YAML string resources through Weblate, ensuring accurate UI display and improved licensing visibility for Greek-speaking users. Contributed to mostafaalagamy/Metrolist by initiating Greek localization, translating a substantial portion of the interface and establishing a scalable workflow for ongoing internationalization. Demonstrated proficiency in localization, mobile development, and translation, leveraging tools like Weblate and version control to improve user experience and support broader accessibility goals across both projects.
