Freelancer Overview

I am beginning my professional journey in AI training data and data labeling, with a strong interest in supporting the development of machine learning models through accurate and consistent annotations. I am comfortable working with structured guidelines and detail-oriented tasks such as image classification, basic object annotation (bounding boxes), dataset validation, and content review. I focus on following instructions carefully and maintaining consistency across large datasets. In addition to image labeling, I am also interested in contributing to voice and speech datasets. I can provide clear voice recordings and assist with audio-related tasks such as speech data collection, validation, and basic transcription. I am reliable, patient with repetitive work, and committed to delivering high-quality audio and annotations that help improve AI systems.
