Developed a JSON-based domain configuration for the is-a-dev/register repository, focusing on streamlining portfolio domain onboarding and centralizing domain settings. The work involved creating a configuration file that includes owner details and supports CNAME-based domain resolution, enhancing consistency and maintainability across deployments. Leveraging skills in JSON, domain configuration, and web development, the implementation improved the workflow for adding new domains by making the process more transparent and traceable. All changes were linked to a specific commit for accountability, and no critical defects were reported during the period, reflecting a focused and well-executed approach to configuration management tasks.
