Data Science Portfolio

Static portfolio for Lianghao Zhan, a Data Science student at Universitat Politècnica de València. It presents six reproducible, public case studies covering data engineering, geospatial analysis, operations research, forecasting, governed machine learning, and NLP retrieval.

This site deliberately distinguishes observed results from modeled scenarios. It does not claim commercial deployments or company work.
