Freelancer Overview

I'm an AI Data Annotator with 3 years of experience reviewing and evaluating written content. I study Mathematics at university which helps me think logically and spot errors quickly. I've worked with AI tools, I know what a good response looks like and I know when something is wrong. I follow instructions carefully, pay close attention to detail and I work well on my own. CORE SKILLS are: Text classification and categorisation Image and video labelling for AI training Reviewing and comparing AI outputs for quality and accuracy Spotting errors and inconsistencies in written content Data cleaning and error correction Following annotation guidelines consistently Strong written English, C1/C2 proficiency Logical thinking and structured reasoning Working independently without supervision Remote work and self-management

Labeling Experience

Yes, I have relevant experience

Yes, I have relevant experience. I have spent 3 years reviewing and evaluating written content, comparing AI-generated outputs, identifying where they fall short and documenting what a better response looks like. I regularly work with AI writing tools and evaluate their outputs for clarity, tone and accuracy. While I haven't done formal data labeling on a dedicated platform, I have been doing the core work of AI output evaluation and content quality assessment in practice.
