Summary
Fei Zhan is a data scientist with 11 years of experience blending rigorous research-grade analytics and production data engineering to drive customer-centric solutions across retail, gaming, and adtech. Currently splitting time between CitrusAd and LoyPal, he builds scalable data platforms and predictive models that translate customer behaviour into measurable growth. His background includes migrating enterprise data warehouses to cloud-native lakes, developing high-accuracy churn and marketing models, and inventing a deep-learning based customer segmentation approach that outperforms traditional clustering in high dimensions. Fei began his career in theoretical physics (Dr. rer. nat., magna cum laude) and brings that quantitative rigor to feature engineering and model validation, including discovering and correcting benchmark errors in peer-reviewed research. Comfortable from supercomputer workflows to PyPI-packaged prototypes, he combines academic depth with a pragmatic focus on productionisation and business impact.
