Developed and delivered a domain configuration file feature for the is-a-dev/register repository, enabling owner and CNAME-driven domain management through a new JSON-based schema. The work involved migrating the configuration structure from a single 'record' to a more scalable 'records' format, supporting future extensibility and maintainability. Personalized configuration was introduced by renaming introduction.json to tusharsk.json, establishing a consistent naming convention for domain files. Focused on configuration management, data management, and file management, the implementation aimed to streamline onboarding for new domains and reduce friction for users. All changes were feature-driven, with clean, well-attributed commits and no major bugs reported.
