Worked on the is-a-dev/register repository to enhance domain management by introducing new JSON-based configuration files that store owner details and DNS records, supporting more reliable domain setup and verification. Focused on backend development and configuration management, the work included adding a domain configuration for _vercel.uzairzia and ensuring data integrity through careful handling of JSON syntax. Addressed a bug related to domain verification by correcting a missing quotation mark in the email field, which improved the reliability of the verification process. Utilized skills in data management and domain configuration, with a technical emphasis on JSON for structured data representation and validation.
