FinTrack Pro approached CodeSwift with a vision: build a financial analytics platform that could handle real-time data streams from multiple sources while maintaining sub-second latency for over 50,000 concurrent users.
Their existing solution was a patchwork of spreadsheets and third-party tools that couldn't scale with their growing user base. They needed a unified platform that would provide instant insights, customizable dashboards, and enterprise-grade security.
The core challenge was threefold: First, we needed to ingest and process financial data from over 15 different data providers in real-time. Second, the dashboard had to render complex visualizations without any perceptible lag. Third, the system needed to support role-based access control for different user tiers.
Additionally, regulatory compliance required us to implement audit trails for every data access and maintain data residency across multiple regions.
We architected a microservices-based solution using Next.js for the frontend and Node.js for the backend services. WebSocket connections ensured real-time data delivery, while PostgreSQL with TimescaleDB extension handled time-series data efficiently.
For the visualization layer, we built a custom charting library optimized for financial data, supporting candlestick charts, depth charts, and custom indicators. The library leverages WebGL for hardware-accelerated rendering, enabling smooth 60fps updates even with thousands of data points.
Role-based access control was implemented at both the API gateway level and within individual services, ensuring defense in depth. We also integrated with their existing SSO provider for seamless authentication.
The project was delivered in three phases over 8 months. Phase one focused on core infrastructure and data ingestion pipelines. Phase two delivered the dashboard framework and primary visualizations. Phase three added advanced features like custom alerts, portfolio tracking, and mobile responsiveness.
Throughout development, we maintained continuous deployment pipelines with automated testing covering over 85% of the codebase. Weekly demos with stakeholders ensured alignment and allowed for rapid iteration on user feedback.
The platform launched to immediate success. Reporting that previously took minutes now completes in under a second, a 3× improvement. User satisfaction scores increased by 47%, and the platform successfully handled 50,000+ concurrent users during peak trading hours.
FinTrack Pro has since expanded their user base by 200% and credits the new platform as a key differentiator in their market positioning.
