Worked on the is-a-dev/register repository to enhance data integrity by correcting ownership metadata and aligning DNS configurations. Focused on updating the jeielmiranda.json file to ensure the username and email accurately reflected the current owner, thereby reducing the risk of misrouting across services. Addressed a bug related to DNS CNAME records, updating them to match the new ownership details and maintain proper domain configuration. Utilized JSON for structured data management and applied data management skills to maintain consistency across repository records. The work emphasized careful attention to metadata accuracy and DNS alignment, contributing to more reliable service routing and ownership tracking.
