At Jiangsu Jinfu Digital Group Co., Ltd, I contribute to an internal healthcare data masking tool built with Python, FastAPI, and React. It supports field-level masking of structured data and sensitive information in clinical narratives, with typical batches exceeding 100,000 records.
I also independently designed and developed a data-volume monitoring module for a healthcare data integration project, using Grafana and Prometheus to monitor synchronization and data-volume changes and Feishu alerts to support anomaly detection. Previously, at Citigroup Services and Technology (China) Limited, I developed React and TypeScript modules for Citi Velocity and helped reduce initial page load time from approximately five seconds to under two.
