Worked on localizing the billing section of the HeyPuter/puter repository, focusing on delivering a consistent French-language experience for users. Utilized JavaScript to implement internationalization and localization techniques, completing French translations for all billing-related terms and messages. Addressed undefined translation keys by replacing them with accurate French text, ensuring that the billing module displayed coherent and complete localized content. The work established a foundation for future localization efforts across other modules, providing traceability through linked commits. No bug fixes or additional features were reported during this period, with all engineering efforts concentrated on enhancing the application's multilingual support.
