Leo Kai

I've prepared, labeled, and validated datasets for AI and automation projects across computer vision, NLP, and autonomous systems.

At AfricaAI Labs, I labeled and categorized training data, maintained a 99% accuracy rate through detailed reviews, and worked with engineers to refine annotation guidelines and workflows. I also trained new annotators on tools, standards, and quality best practices.

I've contributed to projects including GRAPES, where our team produced 20,000 labeled grape images for agricultural analysis, and AVRIDE, where I annotate 3D sensor data through segmentation and cuboid labeling. My work also includes image segmentation for crack detection and autonomous vehicle datasets.

I bring data cleaning, validation, quality assurance, workflow optimization, automation testing, and documentation experience to ML data preparation work.
