Freelancer Overview

I have great experience in data labeling and AI training data preparation, with a focus on delivering high-quality, scalable annotations across domains such as computer vision, and autonomous vehicle systems. My background includes managing large datasets involving image classification, object detection, video annotation, semantic segmentation, and text tagging. I’m proficient with tools like, Labelbox, and hasty, and have contributed to training data for models in autonomous driving, retail analytics, and conversational AI. What sets me apart is a strong understanding of both annotation workflows and AI model requirements, allowing me to bridge the gap between raw data and model-ready datasets. I ensure accuracy through quality control processes, work closely with data science teams on schema design to deliver consistent, high-quality results under tight deadlines. My ability to interpret complex guidelines, apply domain knowledge, and optimize labeling efficiency makes me a valuable asset to any AI training data operation
