Feb 1, 2026February 2026 — govuk-one-login/mobile-ios-one-login-app: Delivered two focused improvements targeting user experience and QA consistency, with measurable business value. Key features delivered: - App Integrity Error Screen: Introduced a dedicated screen to inform users during integrity issues, with analytics tracking to measure usage and failure modes (commit 114baab1be83039a94edfbea9ac2edce5b2a0a2f; DCMAW-18052). Major bugs fixed: - Reference Screenshot Standards Update: Updated reference screenshots to include the text 'app' after the app name to ensure consistency and clarity (commit 9e028b8361b7da4276359954650ad5536102b8cc; #705). Overall impact and accomplishments: - Improved user experience during integrity issues, with added observability via analytics. - Enhanced QA reliability and release confidence through standardized reference screenshots. - Clear alignment with product requirements and measurable business value (reduced ambiguity in UI references, better data for issue monitoring). Technologies/skills demonstrated: - UI/UX considerations for error handling in a mobile iOS app. - Analytics integration for feature visibility and issue diagnosis. - QA/process discipline through screenshot standardization and reference management.
