Developed a JSON-based domain management configuration for the is-a-dev/register repository, enabling configuration-as-code for specifying domain owners and CNAME records. The solution was implemented through a dedicated configuration file, leveraging JSON for structured data representation and Git for version control and traceability. This approach streamlined domain and DNS management by reducing manual steps, minimizing the risk of deployment errors, and improving reproducibility for onboarding new domains. The work demonstrated skills in configuration management, domain management, and configuration-driven deployment readiness, focusing on maintainable infrastructure practices and supporting more reliable, automated workflows for managing domain ownership and DNS settings.
