Gold Clearing Subsystem
The Gold Clearing Subsystem is a backend platform that supports gold trading channels and related clearing operations.
The system provides core capabilities for managing corporate clients, member information, trading relationships, and gold transaction processes. It supports corporate clients and members in initiating gold trading transactions, while ensuring transaction security, operational traceability, and compliance with internal approval workflows.
As a financial backend system, the project placed strong emphasis on data security, transaction reliability, approval control, system stability, and maintainable business processes.
Project Background
The gold trading business required a reliable backend clearing subsystem to manage corporate relationships, member data, trading permissions, and transaction processing.
The project focused on improving the existing business model, strengthening transaction handling procedures, enhancing security controls, and standardizing development and testing practices.
The system aimed to:
- Support gold trading transaction processing for corporate clients and members.
- Manage corporate client relationships and trading-related business data.
- Improve operational control through approval workflows.
- Provide manual handling procedures for exceptional or failed transactions.
- Strengthen sensitive data protection across logs and system processes.
- Improve system reliability through testing standardization and dependency upgrades.
System Architecture
The system adopted a Java-based backend architecture with Spring Boot, Spring Security, Netty, MyBatis Plus, MySQL, Redis, Docker, and Kubernetes. The architecture supported secure transaction processing, backend service integration, data persistence, caching, and containerized deployment.
My Role
In this project, I contributed to business model refactoring, transaction process implementation, security enhancement, approval workflow development, testing standardization, dependency upgrades, and technical documentation improvement.
My work focused on improving both business functionality and system reliability for financial transaction scenarios.
