Fintech Redesign
A comprehensive IELTS preparation platform with course management, payment processing, and user authentication.
Banking made
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.
Key Features
- Customizable widget system
- One-click data export
- Real-time websocket updates
- Predictive search analytics

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.tsconst 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."
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.
"The new dashboard has completely changed how our team operates. What used to take hours now takes minutes."— Head of Analytics, FinCorp
"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.
Skills Developed
Deepened knowledge in WebGL for performance and learned advanced TypeScript generics for safer data handling.
What I'd do differently
I would involve the engineering team earlier in the design phase to better understand API limitations.
