Applied machine learning
Built an early-risk screening workflow from 30 start-of-term features, deliberately excluding prior grades. The app compares six classifiers, tunes Random Forest and XGBoost with GridSearchCV, and exposes prediction, ROC, model comparison, and feature-insight views.
Full-stack web application
Delivered a PHP and MySQL HR platform that brings authentication, role-based access, employee and department management, attendance, leave, payroll, and performance workflows into one operational system.
