Developed a subdomain DNS configuration management system for the is-a-dev/register repository, introducing a declarative, version-controlled approach to managing DNS records and ownership. Leveraged JSON configuration files to capture and automate the setup for the 'dhruvkhanna' subdomain, reducing the risk of manual errors and enabling auditable, repeatable changes. Focused on configuration management and domain management skills, the work established a scalable pattern for onboarding future subdomains efficiently. By shifting DNS management to a configuration-driven workflow, the project improved maintainability and transparency, laying the foundation for streamlined domain operations and minimizing configuration drift in collaborative environments. No bugs were reported.
