Freelancer Overview

I have hands-on experience in data labeling and AI training, primarily focused on text and conversational data. I've worked with platforms like Outlier and Uolo, where I contributed to improving large language models by reviewing AI-generated responses, evaluating their accuracy, tone, and clarity, and providing detailed feedback for model refinement. My work has required a strong eye for detail, a solid grasp of language nuance, and the ability to identify subtle errors in grammar, coherence, or context. What sets me apart is my deep curiosity about how AI learns and my commitment to helping it better understand human language. I approach every task with care and consistency, whether I’m evaluating educational content, dialogue systems, or user-facing communication. I’m passionate about contributing to AI systems that feel more natural, helpful, and human-aligned.
