Worked on the is-a-dev/register repository to implement a domain configuration and ownership metadata system for GitHub Pages. Developed and initialized a JSON-based configuration file to store domain owner details, enabling accurate domain mapping and ownership traceability. Focused on refining CNAME handling and improving the JSON structure to support robust, future-proof domain automation. Utilized skills in JSON manipulation, configuration management, and data management to validate and harden the configuration through automated checks. This work enhanced deployment reliability and streamlined onboarding for new domains, providing a reusable approach to managing domain ownership metadata across multiple repositories using standardized JSON practices.
