What I'm looking for

I’m looking for a role where I can use my AI data annotation and evaluation skills to help build accurate datasets. I enjoy clear instructions, consistent deadlines, and work that rewards attention to detail and reliability.

I’m a freelance AI data labeler/annotator based in Johannesburg, where I support machine learning projects through high-quality labeling and evaluation. I bring very strong listening skills, a strong work ethic, and the ability to work well under pressure while meeting tight deadlines.

From 2019 to 12/2025, I’ve done Image/Video/Text/Audio Annotation, including Bounding Boxes, Polygon work, image segmentation, categorization, transcription, and audio collection. I’ve also completed key points and search evaluation tasks, and I’m confident using both Mac OS and Windows OS for reliable delivery.

Before annotating full-time, I built a solid administrative foundation as an Admin Clerk and Receptionist, organizing and maintaining company files and supporting office operations. I’m comfortable adapting to any given task, and I’m especially interested in computers and system development.
