Freelancer Overview

I have completed several data labeling projects focused specifically on training data preparation for machine learning models. One project involved text categorization and sentiment labeling, where I analyzed short texts such as product reviews and social media comments and classified them according to predefined categories and sentiment guidelines. This required careful reading, identifying context and consistently applying labeling rules to ensure high quality training data.

Labeling Experience

Image annotation

ImageBounding Box
I was drawing bounding boxes around objects and tagging items such as vehicles, people and common objects to support computer vision models. In addition, I have performed data validation and quality review, checking previously labeled datasets to ensure accuracy and guideline compliance. Through these projects, I developed strong attention to detail, the ability to follow strict annotation instructions, and experience working efficiently with large datasets on data labeling platform.
