April 2025: Delivered two PayCal UI enhancements in defra-design/cpr-prototype (PayCal Billing Instructions UX Enhancements and PayCal Run Classification & Details UI Enhancements). Billing Instructions UX includes a dedicated confirmation flow (review/accept/reject), search/filter, dashboard/navigation updates, terminology standardization from 'invoice instructions' to 'billing instructions', addition of a May 2025 section, corrected hrefs, and branding/title consistency. Run Classification & Details UI Enhancements add new run classifications, reclassification of calculation runs, Run Details refinements (removing non-essential classification rows), run status indicators (Initial/Interim/Final/Final/Test, etc.), and UI actions to view, download, and remove classifications, plus text casing tweaks. Impact: improved user guidance and decision accuracy in billing workflows, stronger data governance for run classifications, and more consistent PayCal UI. Technologies/skills: front-end UI/UX refinements, state and navigation updates, terminology governance, design-system consistency, Git-based traceability across multiple commits.
