At Tencent, I deeply participated in the architecture and core development of WeChat Pay’s domestic and international payment engine. Static traffic sharding, multi-tier caching, and distributed transaction models helped sustain 300k+ TPS peak traffic with 99.999% availability.
I architected a settlement and escrow reconciliation system for WeChat Pay Hong Kong, cross-validating internal ledgers, bank statements, and third-party gateways. I also piloted Flink real-time stream computing for settlement.
At Tencent, I designed a distributed real-time risk engine using Drools, Redis, and Pub/Sub for dynamic rule updates and monitoring. I also orchestrated delivery of a corporate credit rating platform that scaled to 3,000+ enterprises.
Previously, at PCH International, I led architectural design for global supply chain systems and B2B EDI integration channels. Earlier, at Tencent and ZTE Corporation, I worked on data warehousing, BI, supply chain systems, and database optimization.
