Hai Le

I am a fourth-year Data Technology student at Van Lang University with a strong foundation in machine learning and data-driven modeling, experienced in working with large-scale datasets and building predictive models using Python, scikit-learn, TensorFlow, and PyTorch. I am also interested in the full data lifecycle, including researching and improving data collection methods, ensuring data quality through cleaning and validation, and collaborating with teams to manage and monitor data workflows.

Researcher Intern - UIT InsecLab - Vietnam
