Challenges in Building a Scalable and Integrated PoS System

The client required a robust cloud-native PoS system that could scale across multiple AWS EC2 instances while maintaining seamless integration with third-party hardware (cash drawers, receipt printers) and external systems. Legacy device compatibility issues, complex API management for large datasets, and the need for real-time monitoring of distributed cloud infrastructure created operational inefficiencies and technical debt.

A retail technology company specializing in cloud-based solutions for brick-and-mortar businesses

Objectives for the Cloud-Native PoS Development Project

  • Create a fully scalable and maintainable cloud-native architecture on AWS
  • Develop cross-platform compatibility for non-standard retail hardware
  • Implement real-time system monitoring and automated resource management
  • Deliver a comprehensive retail management suite with modular features

Core Functionalities and Key Features

  • Order, stock, and cash management systems
  • Loyalty program and customer relationship management
  • Multi-payment processing (card/cash)
  • Employee and return/refund management
  • Real-time auditing and financial reporting
  • Custom on-screen keyboard for legacy devices
  • API adapter for third-party integrations

Technology Stack and Infrastructure Requirements

Angular with TypeScript for frontend

New Relic for monitoring
Jasmine/Karma for testing

Hardware and System Integration Needs

  • Cash drawer and receipt printer communication protocols
  • Custom API adapter for multi-endpoint data synchronization
  • Third-party device drivers for unsupported hardware
  • Payment gateway integrations

Performance and Scalability Expectations

  • Horizontal scalability across AWS EC2 instances
  • 99.9% system uptime with automated failover
  • Real-time data processing for high-volume transactions
  • Role-based access control and PCI-DSS compliance
  • Cross-browser compatibility for web application

Expected Business Impact of the Cloud-Native PoS System
