Worked on the is-a-dev/register repository to deliver a domain configuration feature enabling user subdomain and GitHub Pages integration. Developed a JSON-driven configuration system that captures owner and URL records, streamlining the process of routing user domains to GitHub Pages through improved CNAME handling. Focused on backend development and configuration management, the solution aligned domain settings in JSON to support consistent and reliable deployments. By automating domain setup and reducing manual intervention, this work accelerated onboarding for custom domains and enhanced brand control for users. Utilized skills in API integration and domain management, with JSON as the primary configuration language.
