Mario Mupo developed foundational Azure infrastructure for the pagopa/dx-playground repository, focusing on secure, private deployments for App Service and Function App in the development environment. Using Terraform and HCL, Mario implemented infrastructure as code to enforce private access, virtual network integration, and updated provider and module versions for maintainability. He integrated Azure API Management resources, applying standardized naming conventions to support clear API governance for both front-end and back-end services. By removing external access and hardening security, Mario’s work reduced the attack surface and enabled safer, more controlled deployments, demonstrating depth in cloud infrastructure and automation practices.
