Worked on the is-a-dev/register repository to deliver a domain-mapped, multi-tenant blog configuration system focused on owner-specific branding and scalable onboarding. Developed owner metadata using JSON and established DNS-based CNAME domain mapping, enabling each blog to be linked reliably to its respective user domain. The approach included creating and updating owner.json files and CNAME entries, with a follow-up fix to ensure accurate domain resolution and ownership attribution. Leveraged configuration management and data management skills to maintain full traceability through well-documented commits. This work laid the groundwork for consistent branding and reliable domain mapping across multiple blog tenants.
