• Building complex data experiences (tables/grids, filters, virtualization) with AG Grid or TanStack Table, and rich editors with Tiptap when needed.
• Owning data fetching/caching with TanStack Query; integrate REST/GraphQL APIs and WebSocket streams.
• Improving performance (code-splitting, memoization, virtualization) and UX metrics (LCP/INP).
• Maintaining quality: unit/component tests (Vitest + Testing Library), mock APIs (MSW), visual testing (Chromatic), and error monitoring (Sentry).
• Strengthening DX and CI (Vite, ESLint/Prettier, lint-staged, Husky, conventional commits).
