IOBIT - Perpetual Trading Platform
Lead / sole developer · live at iobit.ai
The Problem
The client needed a full perpetual-futures trading product - not a dashboard on top of someone else's exchange, but the backend, the web app and the mobile app, all built and operated in-house.
What I Built
Three codebases, alone: a Go/Gin backend, a Next.js web application, and an Expo mobile app now on the App Store and Google Play. Authentication is passwordless - users sign EIP-712 messages with their wallet instead of holding a password.
Result
- ▹Go backend with 133 routes and 29 database tables, a WebSocket hub for live market data, background sync workers and Prometheus metrics
- ▹A circuit breaker guards the external exchange API, so an outage upstream degrades the product instead of taking it down
- ▹EIP-712 wallet authentication with replay protection - no passwords stored
- ▹Order placement (market, limit, stop, TWAP), portfolio and PnL tracking, staking and referrals - on web and mobile, in five languages
- ▹Rate limiting and IP blocking at the edge of the API
