Freelancer Overview

I am an experienced AI Data Labeling Specialist with over 8 years of hands-on experience in creating high-quality datasets for machine learning applications. I have worked extensively with image, video, text, and 3D sensor data, delivering accurate and reliable annotations for projects in computer vision, autonomous systems, and natural language processing. I am skilled in a variety of labeling techniques including bounding boxes, segmentation, cuboids, and text classification, and I am comfortable using leading platforms such as Labelbox, CVAT, SuperAnnotate, and AWS SageMaker. Throughout my career, I have managed multi-modal annotation projects, developed annotation guidelines, and performed quality assurance to ensure datasets meet strict accuracy standards. I have also contributed to LLM evaluation and text generation projects, reviewing model outputs for clarity, consistency, and safety. My experience allows me to deliver high-quality, scalable datasets that help AI models perform better and meet project goals effectively.
