React SaaS Dashboard: Charts, RBAC & Dark Mode
SaaS-дашборд: KPI-графики, роли admin/analyst/viewer и тёмная тема на токенах.
RBAC, React, Recharts, TypeScript
Built a React SaaS dashboard for ops leads: KPI charts, filterable tables, saved views, and role-based menus (admin / analyst / viewer). Dark mode with tokenized theme; data from REST with cached queries and stale-while-revalidate. Empty/error/loading states on every widget.
Stack: React, TypeScript, Recharts, React Router, TanStack Query. Replaced a slow spreadsheet ritual; first paint stayed usable on mid-range laptops. NDA: product name withheld.
