December 2025 milestone: Delivered security, scalability, and quality improvements across multiple repositories, enabling safer access to POS data, larger dataset handling, faster queries, and more accurate API contracts. Key features delivered include: - Merchant Authorization Security Enhancement: Introduced header-based merchant ID validation and threw MerchantNotAllowedException on mismatch to secure access to Point of Sale data (commit 9a139e3b7f... - PointOfSale API Scalability: Increased PointOfSaleDTO array maxItems to 100,000 to support larger datasets in API responses (commit 31ef28e5c6...) - Transaction Query Performance Enhancement: Added an index to the transaction table and cleaned up a minor syntax issue to improve query performance (commit c1a8d0308d0...) - API Documentation Contract Correction: Updated OpenAPI spec to correct DownloadRewardBatchDTO property from 'invoiceUrl' to 'approvedBatchUrl' for accurate documentation (commit f503b7e1815...) - Cross-repo Exception Handling Clarification: Fixed exception message ordering for parameter clarity in idpay-payment (commit db3254e78f1...)

November 2025: Delivered cross-repo features with strong business value across pagopa/idpay-payment and pagopa/idpay-merchant, focusing on search usability, document clarity, and security hardening for POS transactions. Key outcomes include a regex-based "+like" filter for GTIN in transaction queries, barcode support in PDFs for discount sections, and robust POS authorization validation with token checks and POS ID verification. Also updated service exception configuration to properly handle forbidden access scenarios. These changes improve transaction retrieval accuracy, streamline processing of discounted documents, and reduce risk of unauthorized data access, contributing to better customer experience and regulatory compliance.

October 2025: Across idpay-payment, idpay-merchant, and securehub infra, delivered targeted reliability, maintainability, and automation improvements that reduce stale data, enhance output clarity, and ensure API consistency. Highlights include centralized Azure Blob Storage configuration via Spring Boot ConfigurationProperties, a 10-day transaction expiration policy with updated tests, expanded JSON-to-PDF support for ONLINE store types, automated pending-transaction cleanup via Kubernetes CronJob, and Swagger/API consistency improvements for the PreviewPayment API.

September 2025 performance summary for core payments and infra APIs. Focused on delivering features that simplify the API surface, improve traceability, and extend refund capabilities, while aligning policy and OpenAPI specifications across two repositories (pagopa/idpay-payment and pagopa/cstar-securehub-infra-api-spec).

Monthly summary for 2025-08 (pagopa/idpay-merchant): Delivered two key outcomes and one critical bug fix, boosting API quality, deployment velocity, and data privacy. Key features delivered: (1) Point of Sale Retrieval API Enhancement — refactored to return a concise POS DTO and added retrieval by POS ID and merchant ID; updated repository/service/controller to align with the new DTO. Commit efaef00e333ba9db0696faebbae2b6f7c51da642; message: fix: [EBE-67] point of sale removed unused fields in response (#170). (2) CI/CD Workflow Upgrade to GitHub Actions with SonarCloud — migrated from Azure DevOps to GitHub Actions with integrated static analysis and quality reporting. Commit e09e965a397591f80cb9af90ae2de9c854edc9c6; message: chore: [EBE-87] Add pipeline code review workflow (#178). Major bugs fixed: removed unused fields from POS response to reduce payload size and improve data privacy. Overall impact and accomplishments: improved API clarity and data privacy, faster and more reliable deployments through automated CI/CD and quality gates, and a leaner response payload. Technologies/skills demonstrated: REST API design, DTO-driven architecture, repository/service/controller refactor, GitHub Actions, SonarCloud, static analysis, and pipeline modernization.

July 2025 performance summary focusing on security, reliability, and API capabilities across three repositories. Key outcomes include standardized Keycloak environment configuration across UAT/DEV/PROD, hardened deployment pipelines with Azure CDN purge and env-var fixes, and delivery of a new Point-of-Sale Details API to enrich merchant data access. These changes reduce deployment risk, improve authentication reliability, and enable richer data integration for merchants and operators.

June 2025 monthly summary for pagopa/cstar-securehub-infra: Delivered a new CDN configuration and edge routing for the Portal Merchants Operator to serve portale-esercenti with reliable routing, proper index and error page handling, and hardened security and caching for microcomponents. This work enhances merchant experience through lower latency and improved security and resilience in the portal delivery layer.
