Rockstar🎓
Top SchoolZiren Wang is a Machine Learning Engineer with five years of experience building end-to-end ML and data science systems, currently applying LTV and propensity modeling to optimize ads and product pipelines at Chewy. He blends rigorous statistical and mathematical training (MS in Computational Science & Engineering, BS in Statistics) with hands-on ML engineering—productionizing models with PySpark, Airflow, MLflow and AWS. His work spans forecasting, causal inference, survival analysis and optimization, and he has driven inventory and transportation projects that married hierarchical spatiotemporal models with real-world operations. Ziren also contributes backend work to open-source LLM API tooling, expanding multi-provider compatibility (Cloudflare, Vertex AI) and stream/error handling for scalable inference. A former Rice University teaching lead, he brings pedagogy and mentorship to cross-functional teams and a track record of squeezing performance and compute efficiency from models. He’s based in the Greater Seattle Area and combines academic rigor with product-focused delivery across finance, supply chain, and marketing science.
