Freelancer Overview

I am a detail-oriented AI Trainer and Data Labeler with over 3 years of experience working on machine learning projects, specializing in text, image, and conversational data annotation. My expertise includes applying complex labeling guidelines, evaluating AI-generated outputs for accuracy and safety, and providing structured feedback to enhance model performance. I have a strong track record in maintaining high quality standards, consistently achieving over 98% accuracy in labeling tasks. I am skilled in using tools like Labelbox, Scale AI, Label Studio, and Prodigy, and have hands-on experience with reinforcement learning from human feedback (RLHF), content moderation, and quality assurance. My background in communication studies and certifications in AI data annotation and responsible AI further support my ability to deliver precise, unbiased, and reliable training data for NLP and computer vision applications.
