Freelancer Overview

I have experience working with structured data, technical documentation, and quality control processes, which are highly relevant to AI training data and annotation tasks. My background includes using Python and SQL for data-related work, reviewing technical materials for accuracy, and organizing large amounts of project information in engineering and supply chain environments. In addition, I actively use AI tools such as ChatGPT and DeepSeek for research, text analysis, and workflow optimization. My work experience has trained me to follow detailed guidelines carefully, maintain consistency, and deliver high-quality results under deadlines. With strong analytical skills, English proficiency, and attention to detail, I am confident in contributing effectively to AI data annotation and training projects.
