Freelancer Overview

Between 2018 and 2021, I worked as a freelance data annotator with Appen, one of the leading AI training data platforms globally. My work spanned text annotation and categorisation, sentiment analysis, and search result relevance rating — tasks that required careful reading, consistent judgement, and close adherence to project-specific guidelines and rubrics. Working within a structured platform interface, I evaluated and labelled content across diverse topics, applying quality standards to ensure outputs were accurate and useful for model training. Beyond that direct experience, my broader professional background has equipped me with skills that translate naturally into AI training work. Seven years of content creation, copywriting, and editorial work have sharpened my sensitivity to language, tone, and meaning, exactly what is needed when evaluating how well an AI response matches a human's intent. I hold a BA in Mass Communication and an MBA with a Marketing specialisation, and I am a native-equivalent English speaker (C2), comfortable working with nuanced, context-dependent language tasks at pace and to a standard.
