Real-time financial data visualization platform built with React and Node.js.
Vault Finance required a high-fidelity analytics platform capable of ingesting millions of financial transactions per day and presenting them as clean, interactive dashboards for portfolio managers.
Key highlights of the project: - Event-driven Node.js microservices consuming live market data feeds - React + D3.js frontend rendering complex candlestick, heatmap, and trend charts - WebSocket architecture for real-time portfolio value updates - Role-based access control (RBAC) for analyst, manager, and executive views - GDPR-compliant data handling with encrypted PostgreSQL storage
The platform now processes over 4 million data points daily and serves 200+ institutional users across 12 countries.
