Developed and delivered a scalable user-domain hosting solution for the is-a-dev/register repository, focusing on automating domain onboarding and management. Leveraging DevOps practices and configuration management, the work introduced JSON-based domain configuration files and a Vercel deployment workflow to streamline provisioning and maintenance of user domains. The implementation included per-user domain verification using DNS TXT records, ensuring auditability and reducing manual intervention in the onboarding process. By integrating Vercel configuration and domain management, the project enabled automated deployment and ongoing oversight of user domains. The work primarily utilized JSON and domain management skills to enhance operational efficiency and reliability.
