Freelancer Overview

I have hands-on experience supporting AI development through data labeling, image annotation, text categorization, search relevance evaluation, and speech transcription on platforms like Appen and Lionbridge. My work has required me to follow detailed guidelines in English, maintain high accuracy, and consistently deliver quality results across projects involving computer vision and natural language processing. I am skilled at identifying errors, ensuring data quality, and adapting quickly to new tools or instructions. With a strong work ethic, attention to detail, and the ability to work independently, I am committed to contributing effectively to any team focused on AI training data or data annotation tasks.
