Worked on the is-a-dev/register repository to implement domain ownership information and DNS configuration for the mj-youn domain. Focused on configuration management and data management, the work involved updating the mj.json file to include accurate domain owner details and configuring the CNAME record to ensure proper DNS routing and ownership visibility. All changes were made traceable to align with governance and onboarding requirements, improving the repository’s state for future maintenance. The technical approach centered on precise JSON data manipulation and careful configuration updates, addressing the need for transparent domain management without introducing new bugs or unnecessary complexity during the process.
