Freelancer Overview

I am an experienced data specialist with over three years in data labeling, annotation, and AI training data quality assurance. My background includes working remotely on projects for Appen and TELUS International, where I evaluated AI-generated content, annotated images and audio, and ensured high dataset reliability for machine learning applications. I excel at following complex instructions, maintaining high accuracy, and meeting strict deadlines. My skills cover data annotation, content evaluation, pattern recognition, and data cleaning, using tools like Excel, Google Sheets, and various annotation platforms. I have contributed to projects in AI text evaluation and dataset structuring, consistently delivering precise and reliable results. I am fluent in English and Swahili, adapt quickly to new tools, and am committed to supporting the development of high-quality AI systems.
