FinTech Modernization

Rebuilding a legacy banking portal into a high-performance React application.

FinTechReactCloud Security

The Challenge

Global Bank Corp needed to modernize their customer-facing portal. The legacy system was:

  • Slow and unresponsive
  • Not mobile-friendly
  • Hard to maintain

Our Approach

We adopted a Strangler Fig Pattern to gradually replace legacy components with modern React micro-frontends. This allowed us to release value early and often without a risky “big bang” rewrite.

Tech Stack

  • Frontend: React, TypeScript, Tailwind CSS
  • Backend: Node.js, GraphQL
  • Infrastructure: AWS (Lambda, API Gateway)

The Outcome

The new portal has transformed the customer experience. It is now the primary channel for 85% of the bank’s customers.

Key Results

Reduced load times to under 800ms, increased mobile usage by 200%, and improved customer satisfaction scores by 40 points.

The Problem

The client's existing portal was built on 15-year-old technology, resulting in 10s load times and poor mobile accessibility. User retention was dropping by 15% annually.

The Solution

We architected a new micro-frontend solution using React and Node.js, enabling incremental migration. We implemented strict security protocols and a modern design system.
