Developed a user-specific domain configuration feature for the is-a-dev/register repository, focusing on scalable multi-tenant management. The solution introduced per-user JSON configuration files with dedicated CNAME records, enabling isolation and personalization for each user’s domain setup. Leveraging skills in API integration, backend development, and data management, the work established a disciplined approach to file management and Git-based change tracking. By implementing individualized file naming conventions, the project improved auditability and onboarding processes while laying the foundation for automated DNS provisioning. The technical approach centered on JSON-driven configuration, supporting the business goal of auditable, scalable domain control without addressing bug fixes.
