I am a detail-oriented data annotation specialist with hands-on experience in linguistic data labeling, audio transcription, and AI data collection for projects with Sigma.AI and other online platforms. My background includes working with text, audio, and video formats, performing semantic and sentiment annotation, speech labeling, and content classification to support natural language processing (NLP) tasks. I am fluent in English and Swahili, with a strong foundation in translation, interpretation, and terminology management, and I am adept at using annotation tools and collaborative platforms. My commitment to accuracy, meeting deadlines, and maintaining high-quality standards allows me to contribute effectively to remote AI training data initiatives across diverse domains.
