During December 2025, Dupsatou developed a security enhancement for the ZoeyVid/NPMplus repository, focusing on the Hurricane Electric DDNS plugin. She engineered a new plugin configuration that enables DNS verification using dedicated Hurricane Electric DDNS credentials, replacing the previous reliance on root account credentials. This backend development effort, utilizing JSON for configuration and API integration, reduced credential exposure and aligned the workflow with security best practices. By documenting the changes through Git, Dupsatou established traceability and set the foundation for scalable, secure DDNS verification across environments. The work demonstrated depth in plugin development and thoughtful credential management within backend systems.
