Developed scalable domain metadata support for GitHub Pages within the is-a-dev/register repository, focusing on architectural improvements and data modeling. Introduced a multi-record JSON structure to enable automated configuration of user domains, updating the data model from a single 'record' to a flexible 'records' array for multiple DNS entries. This approach streamlines domain management and reduces manual setup, laying groundwork for future extensibility. The work centered on JSON as the primary language and leveraged data modeling and front end development skills. All changes were delivered through well-documented, focused commits, emphasizing maintainability and traceability without addressing bug fixes during this period.
