Freelancer Overview

I have experience evaluating and refining AI-generated content through structured data review and annotation tasks. My work involved assessing model outputs for accuracy, coherence, relevance, and logical consistency, while applying detailed guidelines and scoring rubrics. I identified inconsistencies, categorised text by theme and sentiment, and provided clear, structured feedback to improve response quality. This required high attention to detail, strong reading comprehension, and the ability to maintain consistency across repetitive tasks. With a First-Class background in Electromechanical Engineering, I bring strong analytical thinking, structured problem-solving, and precision to data labeling tasks. I am comfortable working independently in remote environments, meeting time-bound targets, and performing self-quality checks to ensure accuracy. My technical and analytical training allows me to interpret complex guidelines effectively and contribute to improving AI system performance in a reliable and consistent manner.
