Lumiko Oiye

I am a multilingual language specialist and certified telc examiner with extensive experience evaluating and instructing German, English, and Portuguese learners. I have worked on language evaluation, annotation, and data-driven quality assurance for AI language models and educational programs.

My background includes delivering integration, literacy, and vocational German courses for adults, conducting oral exams for telc certificates (A1–B2), and performing translation and review of multilingual content to ensure linguistic accuracy. I combine classroom instruction with digital education tools and standardized assessment guidelines to improve learners' grammar, pronunciation, and fluency.

I have practical experience in language data annotation and AI evaluation, and earlier experience as a production engineer, which strengthened my process-oriented approach to quality and assessment. I bring attention to detail, strong cross-language skills, and a commitment to measurable learning outcomes.
