xPoverty: Enterprise Donations Platform
Robust architecture, multiple payment gateways, and comprehensive testing to transform social impact
Project Overview
xPoverty is a donations application developed with enterprise-grade architecture that allows non-profit organizations to receive donations securely and efficiently. The project was built with industry best practices, focusing on scalability, security, and user experience.
The Challenge
Create a donations platform that could handle multiple international payment gateways, comply with strict compliance requirements, and offer a seamless experience on both web and mobile devices.
- •Integration of multiple payment gateways (Stripe and DLocal)
- •Compliance with security and regulatory standards
- •Consistent cross-platform experience (Web and Mobile)
- •Reliable webhook system for real-time synchronization
The Solution
We developed a robust microservices architecture with C# .NET for the backend, ensuring scalability and maintainability. The frontend was built with Flutter, allowing a single codebase for web, iOS, and Android.
Enterprise Backend
C# .NET with clean architecture, CQRS pattern, and Entity Framework Core for efficient data management.
Cross-Platform Frontend
Flutter with BLoC pattern for state management, ensuring reusable and maintainable code.
Payment Integration
Implementation of Stripe for global markets and DLocal for Latin America, with automatic fallback system.
