Real-Time Trading
Crypto Exchange — arz.me
Live markets, wallet, and buy/sell on one Next.js stack — a production exchange, not a brochure site.

Users needed both a public, SEO-friendly landing and a reliable authenticated trading surface. Live market prices and wallet state had to stay consistent across pages without fragile refresh hacks — and the front-end had to coordinate cleanly with backend services.
My role
Led front-end architecture from scratch for the exchange app and landing (barman-tech / graphay context). Built Socket.io market feeds, trading and wallet flows, and shared state with Zustand and TanStack Query while coordinating API contracts with backend.
What I built
- Front-end architecture for marketing landing and authenticated exchange app
- Socket.io live market feeds wired into trading and wallet UI state
- Buy/sell, wallet, live prices, and support flows with Zustand + TanStack Query
- API contract coordination with backend services
Outcome
Production arz.me spans public marketing pages and a dashboard with live market updates and complex trade/wallet UI state — a real exchange surface, not a brochure site.
