Developed a JSON-based domain management configuration for the is-a-dev/register repository, enabling structured handling of user and domain data with support for A records and subdomain configuration. Leveraged JavaScript and configuration management skills to automate DNS provisioning, reducing the need for manual updates and supporting scalable multi-domain management. The implementation introduced a dedicated configuration file, allowing for clear traceability of changes and streamlined updates to domain records, including the addition of a www subdomain. By focusing on DNS management and web development best practices, the work improved operational efficiency and provided a maintainable foundation for future domain management enhancements.
