simple & fast.

We redesigned the entire dashboard experience from the ground up, focusing on speed, clarity, and personalized data views for financial analysts. The result is a highly responsive interface that adapts to user behavior.

The Problem

FinCorp's dashboard suffered from high churn. Users felt overwhelmed by data density. Navigation was too deep, making simple exports take 5+ minutes, leading to frustration and lost productivity.

Our Solution

We modernized the interface with a flattened architecture. The dark theme reduces eye strain for late-night analysts, while vibrant accents highlight critical status changes immediately.

Algorithm Highlight

Implemented a custom Adaptive Sampling Algorithm to render 50k+ data points without lagging the browser thread, maintaining a steady 60fps during zoom/pan operations.

Code Snippet

useMarketData.ts
const useDataStream = (ticker) => {
  const [data, setData] = useState([]);
  useEffect(() => {
    
    const ws = new WebSocket(WS_URL);
    ws.onmessage = (event) => {
       const newData = JSON.parse(event.data);
       setData(prev => [...prev, newData]);
    ;
    return () => ws.close();
  , [ticker]);
  return data;
};

Challenges & Lessons

Data Overload

The sheer volume of real-time data was overwhelming users. We had to find a balance between completeness and clarity.

"Solution: Progressive disclosure. We only show high-level trends initially, revealing granular data on interaction."

speed

Performance Constraints

Rendering heavy charts on older enterprise laptops caused significant lag and poor user experience.

"Solution: Virtualization for lists and Web Workers for data processing kept the UI thread free."

Measurable Impact

Post-launch metrics collected over 3 months showed significant improvements in efficiency.

"Finally, a tool that looks as good as it performs. The dark mode is a lifesaver for night shifts."— Senior Trader, Global Markets

Key Takeaway

User testing early is crucial. We pivoted our navigation strategy twice based on Week 1 feedback.

What I'd do differently

I would involve the engineering team earlier in the design phase to better understand API limitations.
