Developed a JSON-based domain ownership and DNS configuration setup for the is-a-dev/register repository, focusing on standardizing domain onboarding and DNS management across multiple environments. Leveraging configuration management and domain management skills, the work introduced a structured approach that enables scalable onboarding and consistent DNS configuration. The implementation reduced manual intervention and risk during domain provisioning by automating key steps and providing clear traceability through commit tracking. No major bugs were addressed during this period, but minor maintenance ensured stability. This foundation supports automated provisioning and auditing, streamlining domain management processes and enhancing reliability for future onboarding and DNS configuration tasks.
