Joseph Gaitho

I am an AI Trainer and Data Specialist with hands-on experience evaluating language models, performing content annotation, translation, and prompt safety analysis across platforms such as RWS, Appen, Telus International, and GenCrowd. I pair this AI work with practical data analysis—using Power BI, MySQL, and Excel—to clean data, build dashboards, and deliver insights that improve model performance and business decision-making.

As a STEM tutor for the British curriculum in Biology and Chemistry, I design engaging lessons and laboratory experiences that boosted student performance by over 20% and mentored students to success in national science fairs. I have completed thousands of annotation tasks with above-average reviewer ratings and contributed to improved multilingual accuracy and AI safety, while continuously expanding skills in machine learning, SEO, and graphic design.
