October 2024 — pagopa/io-app: IT Wallet issuance flow improvements focused on reliability and test hygiene. Key deliverables were targeted bug fixes rather than new features. 1) IT Wallet Issuance Failure Screen Handling: failure screens render only for actual failures, removing spurious UI when the failure state is null (commit 4a19c6b69b3f22c330a0aef25ef256d5aa289643). 2) Test Artifacts Cleanup for ItwSkeumorphicCard: removed unused mock data in tests; no functional changes (commit c43bc0b07f96a31536cb91647b4b9eaca4ca4eaf). Impact: smoother user journeys during wallet issuance, fewer confusing error states, and lighter test data footprint improving maintainability. Technologies/skills demonstrated: bug fixing in a React Native-based IO app, clear commit messages tied to SIW issues, emphasis on code quality, test hygiene, and cross-functional collaboration.
