Freelancer Overview

Dedicated Freelance Data Annotator with over 3 years of experience in AI data processing. Proficient in handling multi-modal data types including Image, Text, and Audio. My core expertise lies in Bounding Box annotation for computer vision projects, Named Entity Recognition (NER) for NLP tasks, and high-accuracy Audio Transcription. I have a strong track record of maintaining high quality and consistency in large-scale datasets. Previously worked as a Data Processing Assistant at Tech Solutions Co., where I honed my skills in data cleaning and preliminary labeling. I am detail-oriented, adaptable to new annotation guidelines, and committed to delivering precise results to support robust AI model training.

Labeling Experience
