Developed a domain management feature for the is-a-dev/register repository, introducing a centralized koperski.json configuration file to manage domain ownership details and DNS records. This work leveraged JSON for configuration management and data management, enabling a streamlined, configuration-driven approach that reduces manual deployment steps and accelerates onboarding of new domains. The update included standardizing the owner username to support consistent branding across environments. All changes were committed directly to the repository with clear commit messages, ensuring traceability and facilitating future enhancements. The solution established a scalable foundation for domain onboarding and management, focusing on maintainability and operational efficiency.
