Profile: https://flows.cv/andyxiong

I’m a Senior Java Developer with over 6+ years of experience building backend RESTful microservices and frontend UIs using Java/J2EE, Spring, React and Node.js. I leverage Java 8+ features—Streams, Lambdas, Optional and multithreading—to architect high-performance, scalable systems. Proficient in cloud and containerization technologies (AWS, GCP, Azure; Docker, Kubernetes), messaging platforms (Kafka, RabbitMQ), and observability stacks (Prometheus, Grafana, ELK), I deliver end-to-end solutions from API design through CI/CD deployments.

## Work Experience
### Senior Software Engineer @ NetSuite
Jan 2024 – Present | San Leandro, CA
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.

### Senior Software Developer @ TikTok
Jan 2023 – Jan 2024 | San Jose, CA
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.

### Software Developer @ TikTok

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.

### Software Developer @ Tencent
Jan 2019 – Jan 2022 | Guangzhou
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.
