Developed and delivered a domain configuration and verification feature for the is-a-dev/register repository, enabling automated onboarding of custom domains. The work involved provisioning a JSON-based configuration to capture domain owner details and DNS records, and integrating Vercel TXT record verification to establish a verifiable, branded domain path for customers. Leveraging skills in configuration management, DevOps, and domain management, the implementation reduced manual setup and operational risk by establishing a repeatable workflow. This approach streamlined customer onboarding, improved brand trust, and set the foundation for scalable domain management using JSON and modern domain verification techniques without introducing new bugs.
