Architecture Review and Reconstruction: Conduct a comprehensive combing and review of the architecture design of the company’s existing payment systems (including transaction systems, clearing and settlement systems, risk control systems, accounting systems, channel management systems, cross-border payment systems, etc.). Focus on core modules in cross-border payment scenarios such as currency conversion, cross-border clearing channels, and multi-region compliance adaptation. Identify architectural defects, performance bottlenecks, security risks, and scalability issues, and formulate and implement end-to-end architecture reconstruction plans.
