Freelancer Overview

I am a detail-oriented professional specializing in AI training data annotation and evaluation across text, image, audio, and video domains. My experience includes hands-on work with frontier AI model training, multimedia annotation, and human-in-the-loop pipelines, where I’ve performed fine-grained visual analysis, OCR annotation, and model response evaluation for tone, consistency, and factual accuracy. I am skilled in using custom annotation interfaces and maintaining high quality under evolving task requirements. With a strong foundation in prompt engineering, rubric-based assessment, and advanced writing, I bring a keen eye for language and logic to every project. My background also includes creative and technical experimentation with leading AI tools, as well as a proven ability to adapt quickly and work independently in confidential, high-stakes environments.
