Developed a JSON-driven domain configuration system for the is-a-dev/register repository, enabling domain owners to specify DNS records and verification metadata through structured JSON files. This backend solution focused on DNS management and configuration management, allowing for streamlined onboarding by reducing manual setup and centralizing domain ownership data. The approach improved consistency and auditability of DNS records, specifically supporting A and TXT record types for DNS resolution and domain validation. All changes were delivered in two traceable commits, laying the foundation for future automated DNS resolution and verification workflows. The work leveraged skills in backend development and domain management using JSON.
