Develop and maintain reusable UI components and patterns (layout, navigation, tables, filters, forms, modals, etc.) using Tailwind CSS
Use TanStack Query to implement robust server-state patterns (caching, pagination, background refresh, optimistic updates, error handling)
Partner with backend engineers to define API contracts that enable clean, scalable frontend implementation
Improve frontend architecture and team practices (component conventions, state patterns, code review standards, performance budgets)
Ensure UIs are accessible (keyboard navigation, semantic HTML, ARIA where appropriate) and resilient across browsers
Write and maintain tests for critical UX flows
Help drive a strong product 'feel' grounded in our brand through thoughtful micro-interactions, loading states, empty states, and error states
