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 commerce dashboard built with Next.js App Router, TypeScript, TanStack Query, Zustand, Formik, Zod, and typed mock API.
- Server state vs UI state ownership
- DTO → UI model → form values → API payload mapping
- URL filters, mutations, validation, route handlers
