Freelancer Overview

I am an experienced data annotation specialist with hands-on experience in labeling and preparing datasets for AI training projects. I have worked with platforms such as Appen, Telus, and OneForma, contributing to a variety of tasks including text annotation, transcription review, image and video labeling, and audio classification. My work ensures high-quality, accurate, and consistent data to support machine learning and natural language processing models. I have strong attention to detail, organizational skills, and the ability to adapt to different types of data and annotation guidelines. I am proficient in both manual and semi-automated labeling workflows, and I thrive in projects that require accuracy, efficiency, and collaboration with AI training teams.
