Worked on the is-a-dev/register repository to deliver a structured configuration management solution for the Asthowen domain, focusing on user configuration setup and domain reliability. Developed and versioned a new JSON-based configuration file, asthowen.json, which organizes owner details and DNS records for streamlined management. Improved the asthowen.fr domain’s reliability by updating its DNS configuration from a CNAME to a direct URL, reducing indirection and potential resolution delays. All configuration changes were explicitly committed for traceability. The work emphasized configuration management and domain management skills, leveraging JSON to lay the foundation for future onboarding and configuration-driven deployment processes.
