Developed and delivered a Domain Settings Configuration feature for the is-a-dev/register repository, introducing a JSON-based configuration file, cyz.json, to define domain owners and DNS records. This configuration-as-code approach streamlined domain management by reducing manual provisioning and improving consistency across environments. Leveraging skills in configuration management and version control, the work enabled faster onboarding and simplified DNS updates while lowering operational risk. The solution was implemented entirely in JSON, focusing on maintainability and future automation potential. No major bugs were recorded during the period, reflecting a focused and well-scoped engineering effort centered on infrastructure and domain configuration design.
