Scalable API-Driven Data Integration Platform for E-commerce Ecosystems

The client operates an online store hosted on a major eCommerce platform, with multiple personalized services supporting integrations with various external systems. This setup suffers from fragile information sharing, dependency on few skilled developers, and difficulty adapting to new system integration requirements, restricting operational efficiency and scaling potential. Their goal is to establish a unified, resilient, and easily adaptable system infrastructure to streamline workflows, improve customer satisfaction, and support business growth.

A mid-sized online retail company seeking to enhance its system integration, scalability, and operational resilience to support growth across multiple sales channels.

• Develop a comprehensive set of APIs and services to synchronize all eCommerce data with external systems such as payment processors, shipping and logistics providers, subscription management, and billing platforms.
• Create an integration layer that enhances system performance, reliability, and scalability, enabling rapid development and deployment of new features.
• Establish centralized, stable test environments to facilitate continuous growth and operational autonomy for internal teams.
• Implement best engineering practices, including automated testing, code reviews, documentation standards, and architectural guidelines, to ensure maintainability and clarity.

• API layer for secure authentication and communication between internal systems and external services
• Integration services for order management, shipping, billing, and subscription updates
• Automated data synchronization workflows supporting real-time and scheduled updates
• Comprehensive API documentation and architecture diagrams for ease of maintenance
• Internal dashboard for monitoring integration health and performance metrics

• Payment platforms
• Shipping and logistics providers
• Subscription and billing software
• Order management systems
• Printing/document services

• System should support high concurrency, with response times under 200 milliseconds for API calls
• Scalable architecture capable of handling increasing data volume and number of integrations with minimal performance degradation
• Secure authentication protocols and data encryption standards to protect sensitive customer and transactional data
• Automated testing coverage in critical parts of the system to ensure resilience and reduce downtime
• Comprehensive documentation for all APIs, services, and architectural decision points

The implementation of a scalable, API-driven data synchronization system is expected to significantly improve operational efficiency by automating data flows, reducing manual interventions, and enabling rapid deployment of new integrations. This will lead to increased system reliability, a more flexible architecture supporting future growth, and enhanced customer satisfaction through smoother and more consistent service experiences. The project aims to support continued business expansion with a reliable, maintainable, and high-performing integration infrastructure.
