Featured Success Story

An in-depth look at how we helped a leading UK fintech company transform their legacy platform.

FinTech

Modernizing Legacy Banking Infrastructure

The Challenge

PayFast, a UK-based financial services provider, was struggling with an outdated banking platform built on legacy technology. The system was slow, prone to errors, and unable to support modern banking features that customers demanded.

Their internal IT team estimated a 24-month timeline and a budget of £2.8 million to modernize the platform using UK-based developers.

Our Solution

NXTDEV assembled a specialized team of 12 South African developers with extensive experience in financial systems and modern cloud architecture.

We proposed a phased approach that would allow for incremental improvements while maintaining system stability, using a microservices architecture to replace the monolithic legacy system.

Technologies Used

React Node.js Kubernetes AWS MongoDB Redis

Results Delivered

Completed the platform modernization in just 14 months (10 months ahead of original estimate)
Total project cost of £1.2 million (57% cost savings)
99.99% system uptime since launch
90% reduction in transaction processing time
Customer satisfaction increased by 42%

"NXTDEV's South African team delivered what our previous partners said was impossible. They modernized our entire banking infrastructure in record time, at nearly half the cost, while maintaining the highest standards of security and performance. The ROI has been extraordinary."
