Worked on the is-a-dev/register repository to deliver two backend features focused on domain and configuration management over a two-month period. Developed a domain configuration system supporting custom domain verification and DNS A-record setup, enabling seamless onboarding and SSL readiness for new users. Leveraged JSON for code-friendly configuration files, allowing per-user domain deployment and CNAME-backed domain mapping to streamline deployment automation. Ensured accuracy by correcting configuration inconsistencies and validating end-to-end provisioning flows. Demonstrated skills in backend development, DNS configuration, and robust configuration management, with all changes designed to minimize risk to existing deployments while improving branding and deployment isolation.
