Developed a configuration-driven domain management feature for the is-a-dev/register repository, focusing on centralized and version-controlled domain settings. The work introduced a JSON-based configuration file, hymmel.json, which allows declaration of domain owners and DNS records, streamlining the management process. By leveraging configuration management principles and the JSON language, the solution established a reproducible workflow that enhances onboarding and auditability while reducing manual errors. This approach supports future automation and governance across services by making domain configuration transparent and easily maintainable. The contribution addressed a specific need for centralized domain control, laying groundwork for scalable and automated domain management practices.
