Developed a scalable Domain Configuration and DNS Records Management feature for the is-a-dev/register repository, focusing on enhancing domain ownership tracking and DNS provisioning. The work introduced a JSON-based model, rounjiri.json, which stores domain ownership data and a CNAME record for the rounjiri domain. Configuration was refactored to support multiple DNS records by renaming the 'record' field to 'records', improving data management and laying the foundation for future automation. Leveraging skills in configuration management and data management, the developer utilized JSON to ensure data integrity and extensibility, addressing the evolving needs of domain and DNS record administration within the project.
