Overview

PayFlow is a comprehensive financial engine designed to bridge the gap between businesses and banking institutions. By leveraging a high-performance microservices architecture built with Go and Laravel, PayFlow processes thousands of transactions daily with sub-second latency. The system supports complex integration patterns like Virtual Accounts (VA), E-wallets, and Dynamic QRIS, providing merchants with a unified API and a powerful real-time dashboard.

The Challenge

Complex hurdles overcome.

Handling high-volume concurrent transactions during peak hours without data loss or notification delays.

Ensuring 99.99% availability for critical bank integration endpoints that frequently experience timeouts.

The Solution

Architected for success.

Implemented a robust message queuing system with RabbitMQ to decouple payment processing from bank notifications.

Deployed auto-scaling Kubernetes clusters with circuit breakers to manage traffic spikes and gracefully handle external service failures.
