March 2025 performance summary: Delivered cross-repo features and security enhancements across frontend and FDR pipelines, prioritizing business value, reliability, and test coverage. Key features delivered include Commission Bundles Flags (OnUs and Cart) UI, logic, and tests in pagopa-selfcare-frontend, enabling flag controls and improving bundle UX. Major fixes included database environment configuration and CI/CD provisioning improvements across pagopa-fdr, enhancing environment parity and deployment reliability. Security and deployment reliability were strengthened via workload identity adoption across GitHub Actions and Helm in multiple repos, along with Azure Key Vault-based secret/token management for CD. The combination of feature delivery, secure identities, and infrastructure refinements leads to faster, safer deployments with better test coverage and reduced operational risk. Technologies demonstrated include GitHub Actions, Helm, Terraform AzureRM, Kubernetes, Azure Key Vault, and comprehensive end-to-end test automation.

February 2025 performance highlights span four repositories, delivering stability, security, and automation that directly impact business outcomes. Key API stability achieved in pagopa-debt-position with a PIDM-35 OpenAPI recommit, clarifying the contract and reducing downstream integration risk. In pagopa-fdr-2-event-hub, deployment reliability and parity across development, UAT, and production were strengthened through Helm hardening (node affinity, securityContext updates, and privilege escalation controls) and secret handling improvements, plus a targeted fix for Azure Functions secret access. For pagopa-fdr-nodo-dei-pagamenti, new Azure DevOps pipelines enable automated FDR database migrations and Liquibase schema creation across environments with secure Key Vault-managed credentials, accelerating release readiness. In pagopa-selfcare-frontend, the Quicksight dashboard feature enables PSP-specific navigation via a flag and permissions gating, improving user experience for PSP-oriented customers. Overall, these changes reduce risk, shorten release cycles, and demonstrate strong deployment discipline, security-conscious engineering, and customer-focused feature delivery.
