Developed and delivered custom domain support and DNS verification setup for the is-a-dev/register repository, enabling automated provisioning of lusyo.is-a.dev through structured domain configuration files. The solution incorporated JSON-based config files containing owner details, DNS verification records, and A-record provisioning, establishing a scalable workflow for multi-domain management. By embedding verifiable DNS records and owner information directly in configuration, the work streamlined onboarding for users requiring custom domains and improved auditability of domain ownership. The implementation focused on DNS configuration and domain management, with all changes validated and prepared for production deployment. No critical bugs were reported or fixed during this period.
