Freelancer Overview

I have practical experience working with AI training data, including labeling, reviewing model outputs, and checking the quality of generated content. I’ve worked with tools like Label Studio, ChatGPT, and Copilot, which helped me understand how AI models behave and how to evaluate their responses. My background in QA allows me to notice mistakes, inconsistencies, and unclear logic in model outputs. I know how to follow guidelines, compare data with the expected results, and make sure the information is accurate and useful. I also have experience with prompt creation, basic data analysis, and testing AI features, which helps me contribute effectively to AI training and evaluation tasks.
