Monthly performance-focused infrastructure work for 2026-05 in pagopa/cstar-securehub-infra, delivering a MongoDB index on initiativeName to speed up queries and data retrieval; minor pre-commit fixes included in the same commit; collaboration with Stefano Delia.

In March 2026, two major API initiatives were delivered in pagopa/cstar-securehub-infra-api-spec: (1) API Usability and Request Processing Improvements, removing the x-point-of-sale-id header and refactoring inbound policy for invoice updates to streamline processing; (2) Merchant Portal Reward Details API to retrieve batch-level reward information for merchants. These changes reduce client integration friction, improve processing efficiency, and enhance merchant visibility, supported by Swagger/policy updates to ensure contract accuracy. Technologies demonstrated include API design, OpenAPI/swagger, header-based request simplification, inbound policy refactoring, and cross-team collaboration.

February 2026 — pagopa/cstar-securehub-infra-api-spec: Implemented an experimental Merchant Role Management via the x-merchant-role header to differentiate merchant types based on the POS ID presence in the validated token, enabling potential role-based access control and enhanced merchant-type handling. The feature was rolled back across multiple API policy files to preserve production stability and avoid unintended access changes. Key commits include d41069c46a563533834f7c0eee16713f52786059 (EBE-613 x-merchant-role) and the revert d14e114b108aa01649051b8bfd4d6c7f8e50c11e.

January 2026 monthly summary highlighting key features and bug fixes across three repositories. Delivered API design enhancements, search capabilities, and operational automation that improve merchant integration, transaction visibility, and resource efficiency. Coordinated multi-repo changes with clear ownership and documentation updates to ensure maintainability and faster onboarding for teams relying on Pagopa Secure Hub APIs.

December 2025 monthly summary for pagopa/cstar-securehub-infra-api-spec focused on delivering two strategic API enhancements, improving merchant reconciliation, and strengthening API governance.

November 2025 performance summary for development teams (pagopa/idpay-deploy-aks and pagopa/idpay-merchant). Key features delivered: - PDV Encryption Environment Configuration (idpay-deploy-aks): Added environment variables for PDV encryption/decryption to strengthen security and enable secure payment processing workflows. - Secure User ID Decryption and ID-based Operations (idpay-merchant): Refactored identity handling to use user IDs for operations, migrated from fiscal codes, and introduced a REST client for decryption to enhance security and regulatory compliance. Major bugs fixed: - Improve error handling when user is not found and validate user ID (idpay-merchant): Clearer exception messages and pre-flight userID validation to prevent invalid processing. - Improve error messaging in ReportedUserServiceImpl and status filtering (idpay-merchant): More accurate error messages and clarified transaction status filtering to improve user feedback and system integrity. Quality and reliability improvements: - Expanded test coverage for error handling and edge cases (ReportedUserServiceImpl and exception handling in PosValidationExceptionHandler): Increased reliability and correctness through targeted tests. Overall impact and accomplishments: - Strengthened security posture across PDV and identity workflows; improved compliance readiness and risk mitigation. - Increased system reliability and observability through targeted tests and clearer error reporting, enabling faster issue diagnosis and resolution. Technologies/skills demonstrated: - Security configuration via environment variables and encryption/decryption workflows. - REST client integration for decryption processes. - Robust error handling, status filtering improvements, and test-driven development with expanded test coverage.
