Frontend Engineer focused on React, TypeScript, Next.js, product UI, and frontend architecture.
I build maintainable interfaces for data-heavy products: typed API boundaries, state ownership, accessible UI states, performance-aware lists, and reusable components.
Internal operations dashboard for reviewing, managing, and publishing partner offers. Built with Next.js App Router, TypeScript, TanStack Query, Zustand, Formik, Zod, Tailwind, Radix UI, and a typed mock API.
