Worked on the is-a-dev/register repository to deliver two foundational features focused on data and domain management. Developed a centralized user profiles data management system by introducing a liu.json file, which consolidates user information and records for improved governance and traceability. Additionally, updated the CNAME configuration within the same JSON file to point to a new domain, enhancing domain reliability and supporting consistent branding. The work emphasized clear, auditable commits and robust file handling practices. Leveraged JSON for structured data storage and configuration, applying skills in data management and domain management to streamline user information workflows and domain configuration processes.
