2025-10 Monthly Summary: Business value delivered across four repositories with targeted feature toggles, live data enablement, UI maintenance controls, and flow enhancements. Key outcomes include offboarding HMPYOI Lewes and Berwyn with Norwich NWI directions disabled in pre-prod and prod, expansion of live prison data for Lewes, Berwyn, and Norwich (including Norwich AA service), and disabling the Whereabouts UI for Lewes, Berwyn, and Norwich with appropriate maintenance mode. Session cancellation flow enhancements delivered improved user feedback, pre-selection of cancellation reasons, history preservation, data existence checks, and added test coverage. Allocations flow robustness introduced redirect logic to route to the allocations dashboard when essential journey data is missing. Overall impact: reduced operational risk, improved data accuracy, smoother user journeys, and stronger test coverage. Technologies/skills demonstrated: config-driven feature flags (WHEREABOUTS_DISABLED), live data integration, UI maintenance mode, redirect handling, and cross-repo collaboration with test automation.
