What I'm looking for

I seek roles focused on high-quality data annotation and QA within collaborative teams, offering clear standards, timely feedback, and opportunities to improve annotation workflows.

I am a detail-oriented Data Annotator with hands-on experience labeling image, video, and text datasets for AI and machine learning projects. I consistently deliver high-quality annotations using tools such as V7 Darwin, Labelbox, and CVAT, achieving accuracy rates above 99% and meeting strict production targets.

I collaborate closely with QA and project teams to identify labeling challenges and improve workflows, maintain thorough documentation, and adhere to data privacy standards. My background includes work at Digital Divide Data, Innodata Kenya, and AI Data Solutions, and I hold a Diploma in Information Technology and related certifications in data annotation and digital literacy.
