Here's Siyuan Feng, a data analyst at a legal service company. I served as the sole automation developer for an enterprise TestDataManagement program. I built Python/SQL pipelines for AI-assisted sensitive-data discovery, masking recommendations, metadata logging, evidence generation, and post-masking validation.

The field I'm interested in is Data Masking, Privacy Engineering, Open-Source Tools and Python/SQL.
