August 2025 — National Document Repository: UX enhancements and code cleanup focused on improving reliability and maintainability for document uploads. Key outcomes include an auto-scroll-to-validation-errors feature during document upload, refinements to the DocumentSelectOrderStage and DocumentSelectStage to streamline the upload flow, and a targeted cleanup removing an unused component to reduce dead code. A reliability fix for error navigation scrolling was implemented, and the codebase was slimmed by removing the PatientSimpleSummary component and its tests. These changes collectively reduce user friction, speed up error resolution, and simplify future maintenance. Technologies and skills demonstrated include front-end UX refinement, targeted bug fixes, refactoring and code cleanup, and commit-driven development with PRs PRME-164 and PRME-228.
