Freelancer Overview

I have hands-on experience in AI data annotation and training data evaluation, including ranking, scoring, and reviewing AI-generated responses for quality, clarity, relevance, and safety. I have worked on tasks such as text classification, sentiment analysis, named entity recognition (NER), and multi-label tagging, as well as rewriting model outputs to improve accuracy and user experience. My work involves applying structured guidelines, identifying bias and sensitive content, and ensuring outputs meet AI safety and policy standards, while maintaining high consistency in fast-paced, high-volume environments. What sets me apart is my strong foundation in journalism and communication, which enhances my ability to verify information, detect subtle bias, and interpret user intent with precision. Combined with my experience in support roles, I bring a detail-oriented, human-centred approach to AI evaluation balancing quality assurance, ethical judgement, and guideline adherence. I am confident working with ambiguity, structured evaluation frameworks, and continuous feedback loops to improve model performance and training data quality.
