About

Linguistics professional and ESL educator with hands-on experience in AI language model training, data annotation, speech evaluation, and multilingual NLP projects. I work at the intersection of language, education, and artificial intelligence. I have contributed to large-scale AI speech, text, and emotional wellness projects, evaluating American and British English audio, annotating multilingual datasets, and supporting machine translation, TTS, and dialogue quality evaluation. I have processed 3,000+ audio and text samples while maintaining strict quality and accuracy standards. Alongside AI work, I am an experienced English Language Teacher and ESL Instructor, teaching elementary, middle, high school, and adult learners using internationally recognized curricula. I design engaging lessons, assess language proficiency, and integrate educational technology to support learner progress. I also work as a freelance translator and content specialist (Arabic ↔ English), delivering high-quality translation, proofreading, and content review across legal, business, and educational domains. Core interests: AI & NLP, linguistic data annotation, speech and audio evaluation, ESL instruction, and multilingual content quality.
