AI Trainer specializing in Swahili and English language evaluation for multilingual AI.
KenyaWhat I'm looking for
I’m a Senior Swahili Language Specialist and AI Trainer with over five years of expertise in AI training, language evaluation, transcription, teaching, and freelance linguistic analysis. I train and evaluate AI language models for grammar, contextual reasoning, fluency, and factual consistency through prompt evaluation, response ranking, and multilingual quality assurance.
I’m also deeply hands-on with linguistic analysis across semantics, syntax, morphology, and cultural context—identifying reproducible language-model errors and documenting actionable recommendations to improve language quality. In parallel, I deliver accurate English and Swahili transcription, subtitles, and annotations under strict deadlines, and I support learners as a Swahili and English language tutor focused on grammar, pronunciation, writing, and communication.
