Developed a self-serve DNS configuration management feature for the is-a-dev/register repository, focusing on onboarding new users through a JSON-based workflow. The work centered on enabling per-user DNS settings by introducing a portable configuration format that supports ownership and DNS record management. Leveraging configuration management skills and JSON, the developer implemented domain routing updates by modifying CNAME records, allowing dynamic changes from sites.ludicrous.cloud to vibe.ludicrous.cloud. All changes were tracked through Git-based commits, ensuring traceability and auditability. This approach improved the readiness and flexibility of onboarding processes in a multi-tenant environment, though the scope was limited to a single feature release.
