Brokerage Platform
Full-stack trading and investment platform with real-time data feeds, portfolio management, and secure transaction processing at scale.
Overview
A full-stack brokerage platform built to handle the demands of real-time trading — live order books, portfolio analytics, and secure transaction processing under concurrent load. The platform serves active traders who expect millisecond-level responsiveness and zero data loss.
The Challenge
The core challenge was reconciling WebSocket live feeds with persistent PostgreSQL state while maintaining strict transactional guarantees. Every price tick needed to propagate to clients instantly without flooding the database, and every trade had to clear atomically with no race conditions.
