Overview

Under the hood

A real-time trading analytics platform that ingests live market data, generates signals, ranks opportunities, and lets users monitor and act on trading activity through a responsive dashboard. As sole engineer I owned it end to end: the low-latency backend, the WebSocket data layer, the ranking engine, broker integration, and the analytics UI.

The system keeps a live view of the market in sync with the client, scoring and ordering opportunities continuously so the strongest surface first, while live positions and account state flow through a resilient integration layer.
