Freelancer Overview

I am a detail-oriented Computer Science graduate with hands-on experience in data annotation, labeling, and quality review for both text-based and structured datasets. My background includes interpreting complex annotation guidelines, ensuring accuracy across large volumes of data, and working independently in remote environments. I have contributed to projects involving text classification, structured data organization, and system testing, where I was responsible for validating labels, resolving ambiguities, and maintaining data consistency. With a strong understanding of AI and machine learning fundamentals, excellent written English comprehension, and a disciplined remote work ethic, I am confident in my ability to deliver high-quality training data that supports reliable AI development.
