Developed a JSON-based domain configuration management system for the is-a-dev/register repository, focusing on scalable and consistent domain onboarding. The work involved designing and implementing a new data structure that supports multiple DNS records by updating the schema from a single 'record' to a flexible 'records' array. This approach reduces manual configuration and streamlines deployment processes, laying the foundation for future multi-entry DNS management. Leveraging skills in configuration management and data structure design, the developer utilized JSON to define domain settings, including owner details and CNAME records, resulting in improved maintainability and adaptability for domain registration workflows within the project.
