Worked on enhancing the razorpay/i18nify repository by developing advanced currency handling features within the i18nify-go SDK. Focused on implementing currency conversion between major and minor units, the work introduced new functions for accurate pricing and multi-currency support. Improved currency symbol retrieval and updated currency information APIs, ensuring robust error handling for currency lookups. Comprehensive unit tests were written to validate all new currency features, emphasizing reliability and maintainability. The project was executed using Go, with a strong emphasis on internationalization and SDK development best practices, resulting in a more versatile and precise currency management solution for Razorpay integrations.
