Freelancer Overview

I am a detail-oriented data annotation and quality review specialist with 3 years of experience working on high-impact US-based projects, including Zillow, Google Maps, and Waymo. My expertise spans LiDAR, camera, and sensor data annotation for autonomous vehicle perception, as well as geospatial data validation and business listing operations. I have a proven track record of maintaining 98–99% accuracy in data labeling, issue resolution, and customer query management while consistently meeting strict SLA timelines. I am skilled in using tools such as Zendesk, Slack, Google Sheets, and specialized platforms like Crowd Compute and Pushpin. My strengths include root cause analysis, problem-solving, and cross-functional collaboration to ensure data integrity and support high-quality AI training datasets.
