For 2025-11, delivered a new Subdomain Configuration Management feature in is-a-dev/register, establishing a JSON-based, structured approach to define domain ownership details and DNS records. The changes create a single source of truth for subdomain settings and lay the groundwork for automated deployments and audits. In this period, we introduced a new configuration file and performed a file rename to align with ownership naming, reflecting ongoing maintenance and clarity. No major bug fixes were required; refactoring and naming improvements contributed to long-term stability and maintainability. The work demonstrates skills in configuration design, version control discipline, and DNS-related config management, delivering business value by reducing manual configuration errors and speeding subdomain onboarding.
