Freelancer Overview

I am a highly motivated and detail-oriented Data Annotation and Quality Analyst professional with over 7 years of experience in AI data labeling, transcription, and dataset evaluation. I have hands-on expertise in CVAT, Power BI, Excel, Python, SPSS, and STATA, and I specialize in annotating structured and unstructured datasets for global AI and machine learning projects. My experience spans video, image, and text data, including tasks such as bounding box and segmentation labeling, transcription, linguistic evaluation (Swahili and English), and quality assurance. I have successfully coordinated remote teams, implemented M&E frameworks, and trained junior annotators to maintain high accuracy standards (98%+). I am passionate about contributing to AI model training with precise, reliable, and well-organized data. I am flexible with work schedules, highly adaptable to new tools and workflows, and committed to delivering timely and high-quality results for global projects.
