Freelancer Overview

I have over 2 years of experience in freelance data annotation and AI evaluation through personal projects, working with text-based datasets to perform classification, tagging, and sentiment analysis. I have evaluated large language model (LLM) outputs by assessing responses for accuracy, relevance, and clarity, and by ranking multiple outputs based on user intent. I have also identified issues such as inconsistencies, factual errors, and weak reasoning, applying structured guidelines to ensure high-quality and consistent labeling. In addition, my background as a Data Engineer and my MSc in Artificial Intelligence have strengthened my ability to work with large datasets, perform data validation, and understand how labeled data directly impacts model performance. I bring a high level of attention to detail, consistency, and the ability to follow complex instructions, making me well-suited for AI training, annotation, and evaluation tasks.

OtherTextClassification
I performed data annotation and classification on publicly available text datasets, focusing on NLP tasks including sentiment analysis, intent classification, and topic categorisation. My work included applying structured guidelines, tagging, and ensuring high consistency and quality for AI model training and evaluation. I also evaluated and ranked outputs from large language models by assessing the relevance, accuracy, and clarity of their responses. • Annotated and labelled text data for tasks such as sentiment and intent detection. • Evaluated and rated LLM responses for model quality assurance. • Identified inconsistencies, hallucinations, and bias in AI-generated outputs. • Maintained detailed documentation of labeling outcomes and model evaluation results.
