Multi-Bank Payment Gateway System
A robust financial transaction processing platform, developed to integrate and manage payments from multiple sources into a single secure flow.
The Challenge
The client, an emerging financial institution, faced fragmented payment processing. Each banking partner required a separate integration, which created latency, high maintenance costs, and an inconsistent experience for merchants.
- ✓ Multiple and complex integrations
- ✓ Long processing times
- ✓ Lack of a centralized dashboard
Technical Solution
We designed a microservices architecture based on Node.js and Python, with a unified API Gateway. We implemented end-to-end encryption and an intelligent routing system that automatically directs transactions to the most optimal available banking channel.
Results
The platform reduced the average payment processing time from 3.2 seconds to under 0.8 seconds. It enabled the integration of 5 new banking partners in just 2 weeks, compared to 2-3 months previously.
+300%
Increase in processed transaction volume in the first year.
Development Process
The project was structured in two-week Agile sprints. We started with a Proof of Concept for the routing mechanism, followed by the development of core services and the progressive integration of each banking partner. Security testing was continuous, with a final external audit.
