Freelancer Overview

I have 2.5years tagging images, text, and audio for model teams. My focus is clear labels, consistent judgment, and catching edge cases fast. Worked on projects like product sorting, content safety checks, and search query matching. I hit 99% quality scores and keep pace on high volume tasks. Strong with shifting guidelines and daily feedback. Comfortable using Labelbox, CVAT, and spreadsheets to track work. Teams rely on me for clean data and fewer reworks.
