Freelancer Overview

I am an experienced AI training and data annotation specialist with over 3 years of hands-on expertise across multi-modal data types, including text, image, video, and audio. My background includes processing and labeling complex datasets for computer vision, NLP, speech recognition, and medical domains, consistently delivering 99%+ accuracy in high-volume environments. I am skilled in using a variety of annotation tools and platforms, performing tasks such as semantic segmentation, object detection, sentiment analysis, transcription, and linguistic evaluation. My strong command of English and Zulu, combined with TEFL certification, allows me to handle both linguistic and localization projects with cultural sensitivity and precision. I excel at following detailed guidelines, ensuring annotation quality, and independently managing remote projects with strict adherence to deadlines. My commitment to quality and continuous improvement makes me a reliable contributor to any AI training or data labeling initiative.
