Real-Time Trading
Crypto Exchange — arz.me
Full frontend I built myself — landing plus authenticated exchange (wallet, buy/sell, live prices); other disciplines were a team.

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
As a freelance frontend developer I built the full frontend for arz.me myself — public landing and authenticated exchange app; other tech and design members were a team. 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.
