• Develop and maintain RESTful APIs and RPC interfaces, ensuring efficient and secure data exchange between front-end applications, internal platforms, and external systems.

• Participate in system design and data synchronization strategies for multi-DC (Multi-Data Center / Multi-VGeo) architecture, solving distributed challenges such as cross-region replication lag and read-after-write consistency.

• Monitor and optimize system performance, identify and resolve potential bottlenecks, and improve system throughput and response speed.
