Freelancer Overview

With a background in a state-owned big data enterprise and daily hands-on use of AI tools (ChatGPT, Gemini, Kimi, Vibe Coding), I bring strong data handling discipline, attention to detail, and prompt engineering skills to annotation and model testing tasks. I am experienced in processing structured data, identifying edge cases, and following complex labeling guidelines.<br/><br/>What sets me apart is my ability to combine data accuracy with creative AI fluency — plus multimodal experience in video editing and content creation — making me well-suited for text, image, or video annotation projects. I adapt quickly to new platforms and focus on delivering reliable, high-quality training data.
