Developed and delivered a domain and subdomain management feature for the is-a-dev/register repository, focusing on onboarding new tenants and improving multi-tenant domain governance. The work involved configuring DNS records and integrating deployment verification through Vercel by adding a TXT verification record, ensuring reliable and automated domain provisioning. Leveraging skills in DNS configuration, JSON, and domain management, the implementation included owner metadata and streamlined the process of associating subdomains with deployment workflows. This approach reduced manual steps for domain setup and enhanced the reliability of deployment verification, supporting more efficient and scalable management of domains within the multi-tenant environment.
