Worked on the is-a-dev/register repository to deliver a domain configuration management feature using JSON. Developed a system that governs domain ownership, DNS, and verification records through declarative JSON files, enabling automated onboarding and reducing manual configuration steps. Implemented domain entries for a specific domain, including owner details and DNS records, and created a dedicated JSON file to streamline Vercel domain verification workflows. This approach improved security and compliance by making ownership data explicit and enhanced traceability through detailed commit documentation. The work focused on configuration management, domain management, and domain verification, utilizing JSON as the primary language and format.
