Developed a Domain Configuration Management feature for the is-a-dev/register repository, enabling automated deployment of domain settings for adandev.netlify.app and Tag-web.netlify.app. Leveraged JSON for configuration files, introducing support for multiple DNS records and refining CNAME handling by removing protocols and enforcing lowercase normalization. Focused on DNS configuration, DevOps practices, and configuration management to reduce manual intervention and improve consistency across domains. Migrated configuration keys to align with Netlify DNS requirements, establishing a scalable approach for future multi-domain deployments. This work laid a foundation for reliable, maintainable domain management and streamlined the process of managing DNS records through structured data modeling.
