Gravity

With the rapid growth of e-commerce, the company’s strategic focus gradually shifted from offline operations to online channels. To better integrate internal resources and streamline communication with multiple e-commerce platforms, the Gravity project was initiated.

Gravity is a middleware integration platform that connects internal enterprise systems with external platforms, including e-commerce channels, regional business systems, logistics services, and membership platforms. It provides unified data synchronization and inter-system communication across key business domains such as product management, membership services, sales operations, order processing, and logistics tracking.

By acting as a centralized integration hub, Gravity improves operational efficiency, data consistency, system reliability, and cross-platform collaboration across the enterprise.

Project Background

Before the Gravity platform was introduced, different business systems communicated with external platforms through scattered and tightly coupled integration logic. This made system maintenance difficult and increased the risk of data inconsistency, duplicated integration work, and unstable message delivery.

The Gravity project was designed to standardize system integration and provide a unified middleware layer for internal and external communication.

The platform aimed to:

Centralize integration between internal systems and external e-commerce platforms.
Improve data consistency across product, membership, sales, and logistics domains.
Decouple business systems through message-based communication.
Improve message reliability through retry mechanisms and scheduled compensation tasks.
Standardize API security, request forwarding, and integration workflows.
Support future business expansion across online channels.

System Architecture

The system adopted a microservices-based architecture using Spring Cloud, RabbitMQ, Redis, scheduled jobs, containerized deployment, and CI/CD tooling. It supported asynchronous communication, request routing, API security, workflow orchestration, and reliable message delivery between different systems.

My Role

In this project, I worked on business integration module development, message reliability improvement, API security implementation, deployment support, code review, task coordination, and junior engineer mentoring.

I also contributed to improving the team’s engineering practices by designing and implementing a standardized code review workflow.
