About the role

Prototype at speed: build clickable mocks and functional prototypes
Ship product features: evolve prototypes into robust releases—drawers, modals, tables, role-aware views, theming, and export/download flows
Design system: set up practical tokens, components, and UI pattern
Auth & routing: integrate OIDC/OAuth SSO behind a gateway, protect routes, and pass user/group claims to the UI
RBAC in UI: render only authorized forums/data; provide graceful “request access” flows for restricted content
Inter-app handoffs: deep-link from a React dashboard to a chat or analytics frontend, passing context via URL/query
Quality & speed: instrument key product events, write pragmatic tests, and hit performance budgets
Documentation: concise READMEs, UI standards, API contracts, and runbooks for smooth handoffs
