Worked on expanding internationalization support in the faker-js/faker repository by adding ISO 3166-1 country codes for Canadian locales, specifically en_CA and fr_CA. This feature integrated new locale data into existing indices, enabling the generation of realistic Canadian region data for both English and French workflows. The implementation focused on enhancing data fidelity for test and demo scenarios, supporting customer-specific requirements for Canadian deployments. Leveraged TypeScript and skills in locale data management to ensure seamless integration with the existing codebase. The work addressed the need for broader locale coverage, improving the realism and utility of generated data across multiple applications.
