Freelancer Overview

I am an AI training and data labeling specialist with over three years of hands-on experience in annotating and curating high-quality datasets for machine learning projects. My expertise spans a wide range of annotation tasks including text classification, named entity recognition (NER), sentiment analysis, image segmentation, audio transcription, and reinforcement learning from human feedback (RLHF). I have worked extensively on platforms like Remotasks, Labelbox, and Atlas Capture, consistently maintaining a quality score above 98% and collaborating with large teams to ensure guideline consistency and data accuracy. My background includes contributing to AI research benchmarks, moderating sensitive content for trust and safety datasets, and providing actionable feedback to improve AI model performance. I am committed to delivering precise, reliable annotations that power robust computer vision and natural language processing solutions.
