Worked on the is-a-dev/register repository to implement domain verification and DNS provisioning for the estares.is-a.dev subdomain. Developed an end-to-end flow that automates domain ownership checks and DNS record creation, streamlining the onboarding of new subdomains. The approach centered on a single, focused pull request, which improved code review efficiency and ensured clear traceability of changes. Updated documentation to support repository readiness and maintainability. Utilized skills in DNS configuration, domain management, and JSON to deliver the feature. The work addressed the need for reliable domain setup processes, contributing to a more robust and transparent domain registration workflow.
