Worked on the is-a-dev/register repository to deliver a user-specific JSON configuration enabling per-user GitHub Pages deployment. Focused on configuration management and data serialization, the work involved creating a new JSON file containing owner details and a CNAME record tailored for a specific user. Addressed a schema issue by updating the configuration structure, changing the key from 'record' to 'records' to support multiple DNS entries and ensure compatibility with automated deployment workflows. All changes were version-controlled and integrated into the repository’s deployment process, demonstrating attention to data structure management and proficiency with JSON for configuration and schema correction tasks.
