Worked on the is-a-dev/register repository to deliver a foundational domain configuration capability, introducing a JSON-based approach for managing domain settings. Developed and integrated a new configuration file, mohsen.json, to specify domain ownership and DNS records, which streamlined the provisioning process and reduced manual setup steps. Leveraged skills in JSON management and domain configuration to establish a version-controlled, auditable workflow that minimizes DNS misconfiguration risks. This work laid the groundwork for automated domain provisioning and supports future scalability across development, staging, and production environments. The solution focused on maintainability and efficiency, enabling faster onboarding of new domains without manual intervention.
