PROFILE
Dan Rukas
Dan Rukas developed and modernized the OHIF/Viewers front-end over eight months, focusing on UI consistency, maintainability, and workflow clarity. He migrated core panels and controls to a unified component library using React and TypeScript, introducing features like themeable overlays, segmentation icon sets, and settings-driven UI toggles. Dan refactored legacy components, centralized state management, and improved accessibility by consolidating controls and updating documentation. His work leveraged Tailwind CSS and the Context API to streamline styling and configuration, resulting in a more scalable, responsive interface. The depth of his engineering enabled faster feature delivery and reduced future maintenance across the repository.

Sep 1, 2025Month: 2025-09 — OHIF/Viewers delivered a settings-driven UI improvement for Segment Label Display. The control was moved from the toolbar to the settings panel, with a new switch to enable/disable the display of segment names on hover. This consolidates related UI settings, improving organization, accessibility, and overall user experience during segmentations review. No major bugs were reported in this scope; changes preserve existing functionality while reducing toolbar clutter and aligning with a settings-first UI pattern.
