Worked on the is-a-dev/register repository to deliver a domain configuration enhancement focused on streamlining DNS management. Developed a new JSON-based configuration file, sfc.json, to centralize domain settings such as owner and CNAME, reducing manual steps and improving deployment reliability. Enabled scalable DNS management by restructuring the data model, renaming the single 'record' field to a multi-record 'records' array. This adjustment enhanced configuration flexibility and minimized the risk of schema misconfiguration. The work demonstrated skills in configuration management and data structure management, leveraging JSON to create a more maintainable and scalable approach to domain configuration within the project.
