Freelancer Overview

I am a C2-level English language specialist with extensive experience in data annotation and quality assurance for AI training datasets, particularly in image-based Question & Answer projects. My work focuses on precise text extraction from visual sources, rigorous classification and labeling, and reconstructing answers to ensure clarity and independence from context. I excel in detecting errors, ensuring logical consistency, and adhering strictly to annotation guidelines. Using web-based annotation platforms and QA review dashboards, I consistently deliver high-quality, publication-ready data within tight deadlines. My strong attention to detail and commitment to guideline compliance have allowed me to achieve high inter-annotator agreement and align closely with gold-standard benchmarks. I am available for remote, long-term projects and am dedicated to supporting robust, accurate AI systems.
