Developed a country code mapping enhancement for the razorpay/i18nify repository, focusing on backend improvements using Go. Built and integrated the GetCountryCodeFromAlpha3 function to convert ISO 3166-1 alpha-3 country codes to alpha-2, addressing the need for consistent country code usage across localization and analytics modules. The implementation reduced mapping errors and improved data uniformity throughout the application. Maintained clear traceability by referencing the related issue and providing descriptive commit messages, supporting future maintenance. The work demonstrated attention to detail in backend development and contributed to more reliable internationalization workflows by standardizing country code handling within the codebase.
