Senior🎓
Top SchoolQimin Zhang is a Senior Data Scientist based in New York with six years of experience delivering production-grade analytics and ML solutions across advertising, clinical trials, and research settings. Trained in biostatistics at Columbia, he combines rigorous statistical modeling (propensity, XGBoost, time series) with big-data engineering skills—PySpark, AWS EMR/S3, Airflow, Docker—to manage 100TB+ datasets and run weekly CI/CD graph builds for cross-device identity. At Nielsen he maintained 500+ models and constructed a semi-supervised graph linking billions of identifiers for person- and household-level targeting, while at Attain he built a live purchase feed covering the entire U.S. population. He also has hands-on research experience developing group-level ICA for brain signals on HPC, reflecting a knack for translating complex algorithms into scalable pipelines. Colleagues rely on him for technical mentorship, pragmatic delivery, and bridging statistical rigor with production engineering.
