Developed a domain configuration feature for the is-a-dev/register repository, introducing a new JSON configuration file to define owner details and DNS records for a portfolio site. Leveraged configuration management principles and a config-as-code approach to enable declarative domain provisioning, which streamlines onboarding and ensures consistent environment setups. The work focused on reducing manual DNS configuration steps and supporting repeatable deployments. Utilized JSON for structured configuration and applied version control best practices to manage changes. No major bugs were reported during the period, reflecting a focused and well-scoped implementation that addressed domain management automation for the targeted use case.
