Worked on the is-a-dev/register repository to enhance domain onboarding by introducing a JSON-based configuration system for storing owner details and DNS records. Focused on improving the onboarding workflow, the work centered around JSON manipulation and configuration management to ensure data integrity and scalability for managing multiple domains. Addressed a data-model limitation by renaming the DNS field from 'record' to 'records', enabling support for multiple DNS records and preventing data representation issues. The approach emphasized robust data formatting and domain management practices, laying the foundation for a scalable onboarding process using JSON as the primary language for configuration and data handling.
