Christian Busshoff developed and refined a comprehensive front-end component library for the SchwarzIT/onyx repository, focusing on robust UI/UX, theming, and accessibility. Over 13 months, he engineered features such as responsive sidebars, advanced data grids, calendar selection modes, and notification centers, integrating technologies like Vue.js, TypeScript, and SCSS. His work emphasized maintainable design systems, localization, and automated testing, including Figma plugin development for asset synchronization. By addressing layout stability, form validation, and cross-browser compatibility, Christian delivered solutions that improved developer velocity and end-user experience, demonstrating depth in component architecture, state management, and seamless integration of design and code.

Month: 2025-08 — This period delivered a suite of UI and tooling enhancements in SchwarzIT/onyx, expanding the component library's capabilities, improving mobile usability, and strengthening robustness through tests and better APIs. The work emphasizes business value by improving UX, reducing maintenance, and enabling faster product delivery across teams. Key features delivered: - Mobile-responsive OnyxSidebar with a drawer and FAB: adds responsive behavior for small screens, integrates a global FAB provider, and updates OnyxAppLayout to manage defaults. - Figma Icon Library Sync Plugin: automates synchronization of icons from a source file to a target page, creating/updating icons and removing obsolete ones to maintain library consistency. - OnyxFileUpload and OnyxFileCard enhancements: introduces file cards with listType control, default rendering slots, status displays, and progress visuals; includes tests and usage examples. - OnyxDialog component: new UI component built on OnyxBasicPopover with slots for headlines, content, and footers; includes examples and tests. - OnyxBreadcrumb grid layout bug fix: resolved grid behavior by moving the onyx-grid-container class to the appropriate element, addressing onyx-grid-max-* issues. - OnyxStepper: added locale-aware number formatting and NaN handling for displayValue, improving readability and robustness. - OnyxSegmentedControl: introduced a required modelValue constraint and visuals/tests for more predictable state management. Major bugs fixed: - OnyxBreadcrumb: fixed incorrect grid behavior by correct class placement to address grid max-* sizing issues. Overall impact and accomplishments: - Strengthened the design system with more predictable, accessible, and maintainable components. - Enabled better mobile experiences and richer file-management workflows for end users. - Improved developer ergonomics through stricter APIs (e.g., required modelValue) and added formatting/testing coverage. - Delivered reusable tooling (Figma plugin) to keep icon libraries in sync, reducing manual maintenance. Technologies/skills demonstrated: - UI component development and integration within a shared design system - Figma plugin development and integration with content/assets governance - Testing and examples for new components, including slots, status displays, and progress visuals - Localization-aware formatting and robust NaN handling for numeric displays
