South AfricaWhat I'm looking for
I am a motivated and hardworking data annotation specialist with hands-on experience labeling text, image, and audio for AI projects. I completed my Matric in 2024 with a Bachelor’s Pass and distinctions, and I bring reliability, fast learning, and attention to detail to dataset preparation.
My experience includes annotated work for Outlier and freelance projects where I ensured high dataset quality through accurate tagging, categorization, and validation using remote annotation tools. I pair technical annotation skills with strong communication, teamwork, and leadership developed as a school prefect and youth coordinator.
I am adaptable, organized, and ready to start immediately, eager to contribute to AI training pipelines and continue developing professionally through training and new responsibilities.
