Christian Alessandro Atzeni contributed to the pagopa/io-wallet and pagopa/io-backend repositories by designing and implementing robust API endpoints, automated email notifications, and operational scripts to streamline wallet management and user communications. He developed features such as fiscal code whitelist verification and management, leveraging TypeScript, Node.js, and Azure Functions to ensure reliability and maintainability. Christian refactored data retrieval logic, enhanced onboarding documentation, and improved CI/CD workflows, addressing both technical debt and operational efficiency. His work included integrating Cosmos DB for persistent storage and automating notification workflows, resulting in resilient backend services and improved traceability across wallet and backend systems.

April 2025 focused on delivering a cross-repo whitelist verification capability for fiscal codes, establishing a reusable API surface, improving resiliency, and aligning API contracts between io-wallet and io-backend. Key outcomes include a new whitelist verification endpoint in io-wallet backed by a Cosmos DB repository and Azure Function handler, OpenAPI 503 error handling, and coordinated tests and changesets; plus a complementary isFiscalCodeWhitelisted() endpoint in io-backend with controller/service integration. These changes enable reliable, programmatic validation of eligible fiscal codes, reduce outage risk, and accelerate downstream processing for wallet and backend services.
