NetSuite provides cloud-based ERP and business management solutions. I led development of a Warehouse Management System (WMS), optimizing inventory tracking, order fulfillment, and logistics workflows. I designed scalable APIs, integrated real-time inventory updates, and implemented automated picking and packing algorithms. This system improved warehouse efficiency, reduced operational errors, and supported seamless integrations with customers’ broader ERP environments.

Bytedance operates content platforms like TikTok, powered by AI. I built a highly available Authorization Service responsible for authenticating and authorizing millions of API requests per second across global platforms. I implemented fine-grained access control policies, optimized token validation pipelines, and ensured regulatory compliance across multiple regions, enhancing security while maintaining low latency and high reliability.

TikTok is a global short-video platform with a massive real-time content and commerce ecosystem. I worked on a Real-Time Risk Control Platform that detects and prevents fraud across millions of transactions and user interactions per second. I built high-throughput streaming analytics pipelines, integrated graph-based anomaly detection, and optimized AI-driven risk scoring models. This system strengthened platform security, protected creators and advertisers, and ensured compliance with fast-evolving global safety and regulatory requirements.

Tencent is one of the world’s largest technology and internet companies. I led development of a Large-Scale Promotion Management Platform for Tencent’s e-commerce ecosystem, supporting dynamic creation and orchestration of promotional campaigns across millions of products. I built backend services for campaign scheduling, user-level targeting, and real-time performance analytics. This platform enabled Tencent’s marketing teams to launch complex, data-driven promotions more efficiently, significantly boosting user engagement and revenue growth.
