Start a ProjectThe Challenge
The client approached us with a legacy monolithic architecture that was struggling to scale during peak traffic hours. Their database queries were slow, taking over 3 seconds to load user dashboards, and the UI was outdated, leading to a massive 45% drop-off rate among new users during the onboarding process.
"We needed a technology partner who didn't just write code, but understood the extreme security and scalability requirements of the financial sector."
Our Solution
We completely decoupled their legacy system into scalable microservices. We implemented a modern frontend with Server-Side Rendering (SSR) for blazing-fast load times. The backend was rewritten using Node.js and deployed on an auto-scaling AWS Kubernetes cluster.
Key Engineering Highlights:
- ✓Zero-Downtime Migration: Successfully migrated 50TB of data without interrupting current active users.
- ✓Biometric Security: Integrated native FaceID and Fingerprint SDKs for military-grade authentication.
- ✓Real-time Architecture: Built a WebSocket infrastructure using Redis for instant transaction notifications.
The Results
Post-launch, the application saw an immediate surge in user retention. The new microservices architecture reduced cloud infrastructure costs by 30% while handling 5x the previous traffic volume seamlessly.
