The Challenge
FinanceFlow needed a real-time dashboard that could handle millions of market events per day without any perceptible lag. Their existing solution was built on legacy jQuery and collapsed under load.
Our Solution
We rebuilt the entire frontend using React with server-sent events for real-time data streaming, a custom D3.js charting library, and a Node.js backend optimised for high-throughput event processing.
Results
The new platform handles 2M+ daily events with under 50ms end-to-end latency, a 10× improvement. Page load time dropped from 8s to under 1s. Client reported a 34% increase in active user sessions.
