I’m Johnson Makala Ngui, an AI Data Annotator and Reviewer with over 5 years of hands-on experience on large-scale Generative AI and machine learning training projects. I specialize in text, image, video, and multimodal annotation, prompt-response evaluation, and quality assurance, with a strong understanding of annotation guidelines, model behavior, and reviewer-level quality control across production AI systems.
In roles at Avala AI, Outlier AI, and Remotasks, I have consistently delivered high-quality datasets, identified ambiguous or unsafe outputs, and provided actionable feedback to teammates while maintaining throughput and strict quality standards. I thrive in instruction-heavy, rule-based workflows and bring meticulous attention to detail and consistency to every project.
