John Mugo

I am a motivated linguistics and AI enthusiast with strong command of English grammar, writing, and communication, focused on producing high-quality training data for NLP systems.

I have hands-on experience in annotation, content analysis, linguistic evaluation, and QA for AI model training, using tools like Labelbox, Prodigy, and Doccano and platforms such as ChatGPT, Claude, and Gemini.

I bring attention to detail, excellent written communication, and a practical understanding of prompt optimization and data-labeling workflows, aiming to improve model performance through accurate, well-evaluated English datasets.
