About the Client

Solutions Implemented
Discover in detail about the custom solutions we build for the client.

- Role-Based Access Control (RBAC) Framework To strengthen system governance and minimize internal risk, our team implemented a role-based access control mechanism that defined and restricted data access based on user roles. This ensured that sensitive financial information remained protected while empowering teams with access to only the tools and features they needed to perform their roles effectively.
- Real-Time Alerts and Notification Engine We developed a dynamic alerting system that enabled real-time push notifications and in-app alerts for key transactional events—such as payment failures, unusual activity, or account updates. This reduced manual oversight, improved response time for fraud and support teams, and enhanced transparency for both merchants and end customers.
- Scalable Microservices Architecture To support future growth and operational agility, we migrated the legacy system to a microservices-based architecture. This allowed the client to scale individual services independently, reduce downtime during updates, and accelerate new feature rollouts without affecting overall platform stability.
Dashboard Panel
We created a customized dashboard panel for the client’s customers that includes multi-layer features and a user-friendly interface to enable them to track their transactions and automate payments for repetitive orders.
API Integration
We provided third-party integrations with the client’s system to enable smooth merchant onboarding, extend the functionality of their automatic clearing house (ACH) system, and automate email procedures, such as sending transaction emails or loyalty program emails to existing customers.
Fraud Detection System
Our team built a full-fledged fraud detection system for the client to eliminate their security issues and provide a stable and secure backend system for conducting financial transactions.
