Financial Analytics Dashboard
Designed and built a complex financial analytics dashboard processing real-time data streams for enterprise decision making.
The Challenge
The client was struggling with legacy reporting tools that took hours to generate basic financial reports. They needed a real-time analytics platform capable of processing millions of rows of transaction data with sub-second query times.
The Solution
I built a high-performance React frontend paired with a Node.js backend tailored for heavy data aggregation. I implemented advanced charting, Redis for caching, and a robust PostgreSQL data warehouse architecture.
Key Results
- Reduced report generation time from hours to milliseconds
- Successfully handles 5M+ daily transaction records
- Adopted by 500+ daily active enterprise users
