Developed a scalable User Domain Configuration feature for the is-a-dev/register repository, enabling GitHub Pages hosting with support for multiple domain records. The work involved refactoring the configuration model from a single 'record' to a 'records' array, allowing users to manage multiple domains within a single JSON-based configuration file. Leveraging skills in data structure management and front end development, the developer bootstrapped the system with an initial owner file and established explicit commit-based traceability. This approach laid the foundation for automated domain provisioning, reduced manual deployment steps, and improved auditability, all while utilizing JSON and GitHub Pages as core technologies.
