@thebemokaba
I evaluate AI outputs and annotate multimodal data for accurate, safe, high-quality model training.
South AfricaWhat I'm looking for
I evaluate AI-generated text, images, and video against detailed rubrics, assessing factual accuracy, safety, instruction-following, tone, and helpfulness.
I've compared ChatGPT, Claude, and Gemini outputs side by side, documented evidence-based rating rationales, and refined prompts through iterative quality review. I also label and categorise multimodal training data, maintain accuracy and throughput across high-volume batches, and escalate ambiguous cases through quality-assurance processes.
Alongside my BCom Law studies at Eduvos, I apply research, analytical reasoning, and data analytics skills in Excel and Power BI to careful, consistent AI evaluation work.
