Freelancer Overview

I am a detail-oriented and multilingual AI data specialist with over 5 years of hands-on experience in data annotation, labeling, transcription, and translation for machine learning projects. My work with leading global AI companies such as Appen and Remotasks has equipped me to deliver high-quality labeled text, audio, image, and video datasets across diverse domains including healthcare, retail, and technology. I am skilled in using industry-standard tools like Labelbox, CVAT, and the Microsoft Office suite, and have consistently maintained a quality score above 95% while ensuring data security and confidentiality. My background in NLP dataset curation, entity and sentiment tagging, and multilingual data processing in English, Swahili, and Kikuyu enables me to handle complex annotation tasks with accuracy and efficiency. I am committed to delivering results that support robust AI model training and development.
