Rockstar🎓
Top SchoolZhiyong Jiang is a systems-focused data scientist and backend engineer with 11 years of practical experience combining machine learning, mathematical modeling, and distributed game server development. He holds a master's-level Systems Engineering education from UC Berkeley (3.9 GPA) and has applied causal discovery and clustering techniques to real-world problems ranging from COVID-19 policy analysis to logistics price prediction. Zhiyong built end-to-end data pipelines and automated model workflows at Lenovo, achieving prediction errors under 10%, and has hands-on ML experience with supervised and unsupervised methods as well as text mining. As a backend developer he authored core components of a distributed Java game server—implementing state machines, AI tools, message handling and cluster management—demonstrating production-grade systems thinking beyond typical data roles. He also brings teaching and mentoring experience from UC Berkeley courses, making him effective at translating complex concepts for teams and stakeholders. Based in Shenzhen, he’s actively seeking full-time roles bridging data engineering and machine learning where his hybrid analytics-plus-systems background can accelerate production deployments.
