Worked on the is-a-dev/register repository to deliver a domain configuration management feature using JSON for structured domain settings. The solution introduced a dedicated configuration file that defines owner information and DNS records, supporting clear domain onboarding and management. An email field was added to the owner object, enhancing user identification and communication capabilities. All changes were tracked through a transparent commit history, ensuring traceability and deployment readiness. The work focused on configuration management and domain management skills, leveraging JSON as the primary language for data representation. No critical bugs were reported, reflecting a stable and focused engineering effort during the period.
