Arohi Prasad focused on improving localization stability in the mautic/mautic repository by addressing a critical issue in the translations system. She enhanced backend PHP code to catch InvalidArgumentException errors when translations were missing, ensuring the application gracefully fell back to the English locale instead of crashing. To further strengthen reliability, she added targeted tests for pluralization with the fallback locale, increasing test coverage and guarding against future regressions. Her work leveraged skills in backend development, internationalization (i18n), and testing, resulting in reduced crash risk for multilingual deployments and a more robust translation handling process within the codebase.
