Worked on domain management enhancements for the is-a-dev/register repository, focusing on DNS configuration and provisioning for the RTBEngine service. Delivered a feature that registered the rtbengine.is-a.dev domain, set up DNS TXT and CNAME records, and added a direct URL record to streamline service access. Normalized CNAME resolution to ensure consistent DNS behavior and reliable integration with RTBEngine. Employed skills in DNS configuration, configuration management, and domain management, utilizing JSON for record definitions. The work improved domain provisioning speed, enabled faster integration for RTBEngine, and enhanced DNS routing reliability, with all changes tracked through commit-based traceability and version control.
