Oct 1, 2025

Month 2025-10 — Delivered two principal capabilities in pagopa/io-app that enhance user experience and rollout safety, with clear traceability to business goals and engineering standards. Key features delivered: - Institutions Search Session Tracking: added a sessionId parameter to the institutions search API; a sessionId is generated for the first page and reused for subsequent pages to maintain a consistent search session across paginated results. This improves analytics accuracy, user experience continuity, and backend session integrity. (Commit: 3943dbad17011157fd6c0dc9d86bb6764e5fd97d) - Favourite Services Feature Toggle: introduced a feature flag FAVOURITE_SERVICES_ENABLED, wired it through environment files, and exported isFavouriteServicesEnabled in ts/config.ts to control activation without code changes. This enables safer, incremental rollouts and quick rollback if necessary. (Commit: 73abbabee7b1711349244e2b7be8cef011f968c5) Major bugs fixed: - No major bugs reported for io-app in this period related to these capabilities. Focus remained on feature delivery and rollout controls. Overall impact and accomplishments: - Delivered UX and analytics improvements for paginated searches, ensuring session continuity across pages. - Established safer deployment practices via environment-driven feature flags, enabling controlled activation of new capabilities with rapid rollback. - Improved traceability from development work to business objectives (IOPAE-2002, IOPAE-2215) for audits and performance reviews. Technologies/skills demonstrated: - TypeScript, environment-based feature flags, and configuration exports. - API session management across paginated data and integration with analytics/telemetry. - Commit traceability and alignment with project governance (IOPAE items).
