Freelancer Overview

I have several years of hands-on experience in data labeling and AI training across image, text, and audio datasets. My work has included object detection, semantic segmentation, intent classification, and transcription tasks for computer-vision, NLP, and speech-recognition projects. I’m proficient with professional tools such as CVAT, Label Studio, and Labelbox, and maintain a consistent 99%+ quality rating through strict QA and adherence to detailed guidelines. What sets me apart is my cross-modal expertise and precision-driven workflow. I understand how labeled data directly affects model accuracy, and I approach every task with production-level discipline — balancing speed with uncompromising accuracy. I’ve collaborated on large-scale annotation pipelines, reviewed peer output for consistency, and delivered datasets ready for immediate model training and evaluation.
