Mobile app for the #1 crypto exchange in Russia
A native iOS and Android trading app for the largest Russian crypto exchange. Sub-100ms order routing, biometric auth, and a two-tap deposit flow.
What users see. Identity, motion, UI craft, copy.
A trading-grade UI that does not feel like a trading-grade UI. Order book in haptics, charting in 60fps, the deposit flow collapsed from 7 steps to 2. Dark-only by intent: the screen is a tool, not a poster.
What holds it up. Architecture, contracts, infra, latency.
Native Swift/Kotlin clients over a binary WebSocket multiplex. Order routing through a Go gateway with a Redis matching cache. Push-driven order updates, never polled. Biometric keys held in Secure Enclave / StrongBox.
