Developed a JSON-based Domain Configuration feature for the is-a-dev/register repository, enabling declarative management of domain owners and DNS records. The solution centralized domain settings and owner mapping in a single configuration file, streamlining onboarding and DNS provisioning processes. By leveraging configuration management and data serialization skills, the work established a standardized approach to domain setup that supports automated provisioning and reduces manual errors. The implementation focused on using JSON to ensure environment parity across deployments, laying the foundation for future automation. No major bugs were reported during the period, reflecting a focused and well-scoped engineering effort within the project.
