During April 2026, Mili enhanced the medusajs/medusa admin dashboard by implementing British English (en-GB) localization, focusing on both language and regional date formatting. She introduced a new en-GB locale and translation bundle, integrating it with the existing localization pipeline and ensuring seamless loading alongside other languages. Using JavaScript and the date-fns library, she wired European-style date formats (DD/MM/YYYY) throughout admin flows, such as promotions and product setup, to align with UK user expectations. Her work improved user experience for UK customers, reduced regional confusion, and demonstrated solid front end development and internationalization (i18n) skills within a disciplined workflow.
