Freelancer Overview

I have experience contributing to AI training data projects through data annotation, labeling, and quality review tasks. My work involves carefully reviewing datasets, applying clear labeling guidelines, and ensuring that training data is accurate and consistent to support machine learning models. I am detail-oriented, able to follow complex annotation instructions, and committed to maintaining high data quality standards when working with AI training datasets. I have a background in Marketing and hold an MBA in Marketing from Kenyatta University, which strengthens my ability to understand customer behavior, language context, and content interpretation skills that are valuable in AI training tasks such as text classification, sentiment analysis, and content evaluation. My marketing knowledge combined with strong analytical and attention-to-detail skills allows me to contribute effectively to AI training, annotation, and data labeling projects.
