Worked on the is-a-dev/register repository to implement and maintain automated DNS domain records management for new users. Developed a JSON-based configuration system that defines and updates DNS A records, streamlining the onboarding process and reducing manual setup errors. Leveraged skills in DNS management, configuration management, and data modeling to ensure accurate and traceable DNS provisioning. Addressed operational stability by promptly updating A record IP addresses in response to infrastructure changes, maintaining service availability and alignment between configuration and deployment. All changes were tracked through version-controlled commits, supporting auditability and rollback. The work focused on reliability and process efficiency using JSON.
