• 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.

• 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. 
• Knowledge of trading UX patterns (charts, grids, optimistic UI updates, etc.) is highly desirable. 
• 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. 
• Proficiency with Tailwind CSS, shadcn/ui, Radix UI, and component-driven design.
