Worked on the is-a-dev/register repository to establish DNS-based domain verification for streamlined subdomain onboarding. Focused on implementing the foundational setup for the subdomain fofajardo.is-a.dev, this involved configuring TXT and A records and mapping IP addresses to enable automated verification and onboarding flows. Leveraging DevOps practices and networking expertise, the work aligned DNS changes with the subdomain provisioning process, reducing manual intervention and supporting scalable onboarding. The technical approach centered on domain configuration using JSON for infrastructure as code, laying the groundwork for future security checks and efficient subdomain management. No bugs were reported or fixed during this period.
