Freelancer Overview

I have over three years of experience supporting AI training and data labeling projects, specializing in multilingual datasets, content evaluation, and quality assurance. My work has involved annotating audio, video, image, and text data, performing pairwise comparisons, object tagging, classification, and linguistic analysis to improve machine learning model performance. I have completed more than 150 data annotation tasks with a 98% accuracy rate and have extensive experience evaluating AI-generated Swahili and English content for fluency, accuracy, cultural relevance, and safety. What sets me apart is my combination of language expertise and technical annotation skills. As a native Swahili speaker with advanced English proficiency, I have contributed to projects involving AI translation quality improvement, speech recognition training, and multilingual content evaluation. I have annotated over 1,000 audio clips for voice AI systems, reviewed more than 500 machine-translated outputs, and provided structured feedback that helped improve model performance. My strong attention to detail, commitment to quality, and ability to work independently in remote environments enable me to consistently deliver accurate, high-quality training data for AI systems.
