Lê Hoàng

I'm a Computer Science graduate from Hanoi University focused on AI evaluation, data annotation, and data-focused remote work.

In independent AI-assisted research and data analysis projects, I've collected and organized information from multiple sources, verified consistency and relevance, and used AI tools to support research, summarization, classification, and data-processing workflows.

I've built machine learning projects across classification, regression, natural language processing, time-series forecasting, recommendation systems, and image classification. Using Python, PyTorch, torchvision, scikit-learn, and Matplotlib, I've prepared data, trained models, and evaluated performance.

I regularly compare AI-generated responses, identify factual errors and hallucinations, assess relevance and instruction following, refine prompts, and provide structured feedback. I'm available for remote part-time, freelance, contract, and project-based work.
