Developed a domain registration data model and DNS configuration for the is-a-dev/register repository, enabling automated provisioning and centralized management of the zaim.is-a.dev domain. The solution introduced a JSON-based specification that captures owner information and DNS records, supporting reproducible domain setup and scalable onboarding of new domains. By focusing on DNS management and domain registration, the work established a foundation for future multi-domain provisioning workflows and environment parity. The implementation emphasized traceability and rollback capability through version-controlled commits, ensuring maintainability. This initial delivery addressed the need for automated, consistent domain provisioning using JSON and domain management best practices.
