Freelancer Overview

As a Digital Marketing and Cross-border E-commerce Domain Expert with over 6 years of experience, I specialize in the commercial application and qualitative evaluation of AI-generated content (AIGC). My core expertise lies in Prompt Engineering, Multimodal AI assessment (Image & Video), and evaluating Large Language Models (LLMs) for commercial viability. I have extensive hands-on experience designing complex workflows using tools like Midjourney, ComfyUI, and various text-generation models to produce high-converting marketing assets. My professional background allows me to provide expert-level human feedback (RLHF) specifically tailored to e-commerce logic, digital advertising nuances, visual aesthetic evaluation, and anatomical/texture accuracy in AI image generation.
