- Deliver trading-focused UIs with high-FPS charts, responsive data grids, debounced inputs, optimistic updates, and skeleton loading states.
- Manage real-time data using WebSockets or SSE for quotes and order updates.
- Implement forms using React Hook Form + Zod with server-side validation.
- Build modular, accessible UIs with Tailwind CSS, shadcn/ui, and Radix Primitives (plus occasional Chakra UI).
- Write clean, maintainable, and testable code with TypeScript (strict mode), ESLint, and Prettier.
- Ensure quality with Playwright E2E testing, Vitest/Jest, React Testing Library, and accessibility checks.
- Contribute to observability and security practices including Sentry, New Relic, CSP with next-safe, secure cookies, and AuthN/AuthZ.
- Collaborate closely with cross-functional teams to design and deliver scalable solutions.

- Strong command of React 18 features: Suspense, streaming SSR, useTransition, useOptimistic, useDeferredValue.
- Expertise in Next.js 14 tooling: Server Actions, Route Handlers, Middleware, ISR, revalidation strategies, and caching.
- Hands-on experience with performance tuning for mission-critical applications.

- Strong state management skills with TanStack Query, SWR, and server-driven patterns (RSC + Server Actions).
- Experience with forms & validation using React Hook Form + Zod.
- Strong understanding of real-time systems using WebSockets or SSE.
