Developed a new JSON data model for User Profile Management in the is-a-dev/register repository, focusing on owner details and DNS records. This work established a scalable, machine-readable foundation that streamlines profile-driven workflows and automates DNS ownership handling. Leveraging skills in configuration management and data management, the developer structured file-based data contracts to improve data consistency and reduce manual entry. The approach enables downstream services to reliably consume owner and DNS data, supporting future automation and integration. Throughout the month, the developer demonstrated disciplined version control and repository organization, with ongoing minor stability improvements and no major bugs reported during this period.
