Kuaishou operates the second-largest short-video platform globally and a major live-streaming e-commerce business, powered by recommendation algorithms built on large-scale content and user-behavior data. The tech stack emphasizes ML infrastructure (PyTorch, TensorFlow, DeepSpeed) and data processing (Hadoop, Spark, Kafka), reflecting the heavy compute and inference demands of real-time content ranking. Active projects cluster around three areas: merchant onboarding and seller engagement (commercial scaling), model training and data bottleneck analysis (AI infrastructure), and advertising risk control—signaling operational pressure to grow merchant revenue while managing compliance and quality.
