Leonardo Pierangelini developed and enhanced backend workflows across the pagopa/p4pa-payhub-activities and pagopa/p4pa-workflow-hub repositories, focusing on API-driven event processing, notification systems, and reporting pipelines. He implemented RESTful APIs and workflow orchestration using Java, Spring Boot, and Kotlin, introducing features such as legal facts archiving, flexible payment notifications, and robust error handling. Leonardo modernized legacy SOAP integrations, centralized taxonomy validation, and improved data traceability through DTO mapping and versioned reporting endpoints. His work emphasized reliability, maintainability, and cross-repository consistency, delivering scalable solutions that improved data quality, streamlined notification delivery, and enabled phased rollouts for business-critical payment services.

February 2026: Delivered end-to-end SEND stream workflow enhancements, improved error handling, and legal facts archiving across three repositories. Key features include: 1) Notification SEND stream workflow refactor and enhanced error handling in payhub-activities; 2) FetchSendLegalFactActivity to download and archive SEND LegalFact; 3) SEND stream consume workflow endpoint and worker/hub integration enabling end-to-end event processing and archiving; 4) Cleanup and maintenance of workflows with obsolete components removed and version bumps for reliability. Major bugs fixed include improved HttpClient error handling (NotFound paths) and NotRetryable exception management across the SEND stream components. Technologies demonstrated: Java/Spring-based workflows, API design (OpenAPI), TaskQueues, and archiving pipelines. Business impact: higher reliability, reduced manual intervention, faster notification processing, and better data retention compliance.
