Labeling Experience

Freelance Data Annotator

I worked on a polyline data annotation project focused on accurately labelling objects and boundaries within images using line based annotations. The task involved drawing precise polylines around roads, lanes, sidewalks, and other linear structures to help train computer vision models for applications such as self-driving cars and mapping systems. This project required strong attention to detail, spatial awareness, and consistency in labelling according to project guidelines. I used annotation tools to mark objects with accuracy, ensuring the data met high-quality standards for AI training. Through this experience, I developed a solid understanding of image segmentation, quality assurance, and the importance of accurate data in improving machine learning model performance.
