Developed a JSON-driven subdomain configuration feature for the is-a-dev/register repository, focusing on standardizing subdomain ownership and DNS record management. The solution leveraged JSON for data modeling and configuration-driven design, enabling scalable onboarding and consistent governance across multiple environments. By centralizing subdomain provisioning, the work reduced manual configuration efforts and improved traceability through Git versioning. The implementation supports downstream automation for subdomain management, streamlining the onboarding process and strengthening governance. Technical skills demonstrated include backend development and DNS configuration, with a focus on maintainable, configuration-based workflows. No major bugs were addressed during this period, reflecting a targeted feature delivery.
