Paypack Events System – Real-Time Payment Event Processing

Overview

Contributed to the development of Paypack’s event-driven system, which enables real-time tracking and processing of payment transactions. The system allows applications to respond instantly to payment events such as transaction creation, confirmation, and failure.

Key Contributions

  • Developed and maintained backend services for handling payment lifecycle events (e.g., transaction:created, transaction:processed)
  • Implemented webhook-based architecture for real-time communication between Paypack and external applications
  • Designed secure endpoints for receiving and validating webhook payloads
  • Built systems to handle asynchronous event processing and state transitions
  • Improved reliability and consistency of payment status updates across integrated systems
  • Collaborated with frontend and mobile teams to ensure seamless event consumption

Technical Impact

The system eliminates the need for constant polling by leveraging event-driven architecture, allowing applications to receive instant updates on transaction states. This significantly improves performance, reduces server load, and enhances user experience in payment workflows.

Tools & Technologies

The backend was built using asynchronous processing patterns to manage real-time financial events securely and efficiently.
