Freelancer Overview

I am a detail-oriented AI Data Annotator with hands-on experience evaluating and labelling AI-generated content to improve machine learning performance. In my current freelance role, I assess outputs for accuracy, relevance, and clarity, while following structured guidelines to ensure consistency across large datasets. I am experienced in identifying errors, edge cases, and inconsistencies, maintaining a high level of precision in fast-paced, task-based environments. Alongside this, I hold a BSc (Hons) in Business & Marketing from Manchester Metropolitan University and have professional experience as a Marketing Executive, giving me a strong understanding of communication, user intent, and content quality. My background in self-employment and e-commerce has also developed my ability to work independently, manage time effectively, and adapt quickly to new systems—making me well-suited to remote AI training and data labelling roles.
