Freelancer Overview

I have a cross-functional background in product management, AI content operations, and content creation. My work focuses on turning complex requirements into structured tasks, then improving output quality through prompt design, response review, content validation, and iterative optimization. I have been actively using ChatGPT, Codex, and Jimeng for text generation, script writing, content refinement, structured organization, and channel operations, which has built strong capabilities in text understanding, quality judgment, labeling awareness, and feedback-loop improvement. In practice, I have worked extensively on text generation, prompt optimization, response evaluation, content filtering, and quality review. I can define task goals from business needs, identify low-quality outputs, summarize recurring issues, and turn findings into optimization actions. My core strength is combining business understanding with a training and evaluation mindset, making me well suited for text-based SFT, prompt writing, response evaluation, content labeling, and QA-related tasks.
