* Build reusable UI components (TailwindCSS/shadcn/ui) and design systems for prompt inputs, context panes, and feedback collectors.
* Implement client?side observability (OpenTelemetry, Sentry) to monitor latency, errors, and usability of GenAI features.
* Optimize performance through code?splitting, server?side rendering (SSR), and efficient state management (React Query, Zustand, or Redux Toolkit).
* Collaborate with product designers and ML/backend engineers to iterate on prompt engineering, UI/UX flows, and evaluation loops.
* Champion accessibility (WCAG 2.1 AA), localization, and responsive design to reach global audiences.
