Worked on the nuxt-modules/i18n repository to enhance localization configuration by introducing greater flexibility in how locale files are defined and managed. Extended TypeScript type definitions to support both string paths and LocaleFile objects, allowing developers to interchangeably use different formats within the localization pipeline. This approach improved type safety, reducing the risk of runtime errors caused by misconfigured locale sources. The work focused on maintainable API design and backward compatibility, streamlining the localization workflow for both developers and end users. Demonstrated skills in TypeScript, localization, and type definition management, contributing to a more robust internationalization experience.
