The Challenge
CellPay needed a unified platform to manage multiple payment methods cards, bank transfers, and digital wallets under one secure, scalable infrastructure. They required a system capable of handling high transaction volumes, real-time reconciliation, and modular onboarding for merchants.
Our Solution
Saasential architected and developed a full SaaS payment platform with built-in wallet and ledger modules, instant settlement flows, and a robust API layer for third-party integrations. We focused on reliability, regulatory readiness, and ease of merchant onboarding.
Development Process
Requirements Gathering & Compliance Mapping
Conducted comprehensive requirements analysis and mapped regulatory compliance needs across different payment rails and merchant types.
System Architecture & Data Flow Design
Designed scalable microservices architecture with separate services for payment processing, wallet management, ledger reconciliation, and merchant onboarding.
UI/UX Design for Admin & Merchant Dashboards
Created intuitive dashboards for both administrators and merchants, focusing on real-time transaction monitoring, reporting, and easy navigation.
Backend API & Database Implementation
Built robust RESTful APIs with MongoDB Atlas for data persistence, Redis for caching, and integrated multiple payment providers (Stripe, Moov, Astra, Circle).
Testing & Azure Deployment with GitHub CI/CD
Implemented comprehensive testing suite and automated deployment pipeline using GitHub Actions to Azure Static Web Apps for continuous delivery.
Measurable Results
