At Meitu, I built a multi-tenant Credit Platform serving 10M+ users across AirBrush and BeautyPlus, and led a zero-downtime migration of four core services from Azure to OCI that earned the 2025 Outstanding Team Award. I also created a low-code configuration platform that reduced release time from three days to 10 minutes.

Previously at Tencent and Tencent Music Entertainment, I built transaction, pricing, settlement, and real-time order-processing systems supporting enterprise customers, 4,000+ QPS, 500K+ daily orders, and 100M+ user activity records. I also deliver international websites and AI-assisted business workflows end to end.
