Developed and delivered a domain registration and DNS verification feature for the is-a-dev/register repository, enabling automated onboarding for custom domains such as thekr.is-a.dev. The work involved implementing DNS record management, including the setup of verification records and an A record pointing to the service IP, to facilitate secure domain ownership validation. Leveraging skills in DNS management, domain registration, and JSON, the solution streamlined the registration process by reducing manual verification steps and supporting scalable domain onboarding. This approach enhanced both the security and efficiency of domain-based registrations, laying the groundwork for more robust and automated domain management workflows.
