Developed and delivered a domain configuration feature for ru0ya DNS verification and IP mapping within the is-a-dev/register repository. The work focused on automating domain ownership checks and IP address mapping by leveraging DNS TXT and A records, reducing manual setup and streamlining onboarding for new partners. The implementation used JSON for configuration management and applied domain management best practices, with all changes tracked through a single, traceable commit. No major bugs were addressed during this period, but the groundwork was established for future domain expansions and DNS automation, enhancing both security verification processes and operational efficiency for domain onboarding.
