Elmar Geers contributed to the Deltares/fews-web-oc repository by implementing localization and internationalization support using Vue and TypeScript, enabling scalable multilingual user experiences. He refactored components such as TimeSeriesChart.vue to streamline localization logic, reducing maintenance overhead and preparing the codebase for broader accessibility. In addition, Elmar enhanced the UI rendering hierarchy for map-based location selection, adjusting layer ordering so child symbols render beneath main symbols, which improved visual clarity and interaction accuracy. His work demonstrated a strong grasp of frontend development, localization, and UI/UX principles, with careful attention to code readability, maintainability, and disciplined version control practices throughout.

December 2025: Deltares/fews-web-oc delivered a UI Rendering Hierarchy Enhancement for the Clickable Location Layer. By reordering the layer sequence, the child symbol renders below the main symbol, improving visual hierarchy and interaction accuracy in map-based location selection. Included minor code formatting cleanup to support readability and maintainability. No major bugs fixed this month; focus was on feature refinement and code quality. Business impact: clearer location cues, reduced user confusion, and more reliable UI behavior; groundwork for future layer-based enhancements. Skills demonstrated: frontend rendering logic, UI/UX considerations for map interactions, code formatting and linting practices (npm format), and disciplined version control.
