8 Commits • 5 Features
Apr 1, 2025April 2025 — Delivered targeted data-layer migration and reliability improvements in unicef/hope with measurable business value. Key features include migrating data fetching for the individuals list from GraphQL to REST (data model alignment and updated component props), UI reliability improvements to disable issue types by value in the Selection component to ensure stable behavior amid label changes, and Documentation Field Layout Improvements for responsive, better-aligned layouts. Grievances documentation work was completed with a rename to Grievance Supporting Documents and associated test/selectors updates. A safe-path bug fix for head-of-household path construction prevents runtime errors when nested properties are missing. These efforts collectively improved data reliability, UI stability, test coverage, and overall developer velocity. Technologies/skills demonstrated include REST API integration, data model alignment, React component patterns, UI/UX improvements, and defensive programming for nested properties.
