Valtieri contributed to backend and infrastructure projects such as pagopa/idpay-onboarding-workflow and pagopa/cstar-securehub-infra, focusing on onboarding APIs, authentication, and deployment automation. Over six months, he delivered features including multi-environment Keycloak authentication via Terraform, onboarding flow enhancements, and robust error handling using Java and Spring Boot. He refactored onboarding logic for maintainability, improved API contracts with OpenAPI Specification, and enabled safer testing through mock services. His work addressed reliability, compliance, and developer experience by refining status handling, DTO mapping, and caching strategies. Valtieri’s engineering demonstrated depth in API development, configuration management, and cross-repository collaboration for scalable solutions.
January 2026 monthly summary for pagopa/cstar-securehub-infra-api-spec. Delivered a new ChecksError schema and updates to the Merchant API OpenAPI definitions to enable specific error states for transaction-related issues, strengthening error handling and API contracts. Updated processed and suspended endpoints in openapi.merchant.yml to reflect the new error paths. This work improves developer experience, reduces support overhead, and increases reliability of merchant transaction flows. No additional major bug fixes documented for this repository this month.

October 2025 monthly summary: Delivered substantial onboarding-focused enhancements across two repositories: pagopa/idpay-onboarding-workflow and pagopa/idpay-admissibility-assessor. In onboarding workflow, introduced detailed onboarding initiatives API endpoints, refined onboarding status to include a waiting state when budgets are unavailable, and added a detail field to DTOs/models to capture initiative-specific data. Implemented correct JOINED mapping to FAMILY_UNIT_ALREADY_JOINED and improved status logging and error handling with an OnboardingStatusException, mapped to BAD_REQUEST, plus enhanced logging structure and localization readiness. In admissibility assessor, refactored budget availability checks to compute residual budget as total minus spent, enforced a minimum remaining budget of 10000 cents, and sanitized logs to protect sensitive information. These changes deliver richer onboarding data, more accurate user-facing statuses, safer budget validation, and improved maintainability. Technologies/skills demonstrated: API design, REST endpoints, DTO modeling, robust error handling, logging sanitization, and localization readiness.
