Freelancer Overview

I have over three years of hands-on experience in data labeling and AI training data preparation. In my previous roles, I worked on large-scale annotation projects for computer vision and natural language processing models, including labeling complex datasets for object detection, sentiment analysis, and instruction-tuning tasks. I consistently maintained high accuracy rates above 96% while meeting strict project deadlines and quality benchmarks. What sets me apart is my strong attention to detail, deep understanding of AI model requirements, and ability to handle ambiguous cases effectively. I have experience with various annotation tools such as LabelStudio, CVAT, and Scale AI, and I’ve contributed to improving labeling guidelines that significantly reduced inter-annotator disagreement. My background also includes domain knowledge in [coding, general tech, designs], allowing me to deliver high-quality, context-aware annotations that directly improve model performance.
