Freelancer Overview

I have 3+ years of experience in Prompt engineering. I can write prompts to make models fail. I also have experience in rubric writing, as I have done several projects that require writing of rubrics to judge a model. I pay attention to little details, this has helped evaluate model responses in several projects.
