I am a detail-oriented AI voice evaluator and bilingual communicator fluent in Egyptian Arabic and advanced English (C1–C2 CEFR). I specialize in AI chatbot interaction, voice evaluation, and data annotation, consistently following structured guidelines to deliver high-quality results.

As a freelance AI Voice Evaluator, I conduct structured voice conversations with AI chatbots to test fluency and accuracy, evaluate system responses for naturalness and tone, and provide written feedback and ratings that contribute to model improvement.

Previously, I worked as a remote Customer Support Assistant assisting English-speaking customers via chat and voice, maintaining professionalism and accuracy with minimal supervision, and applying strong listening and comprehension skills to resolve issues.

I am available for part-time or project-based work (15+ hrs/week), comfortable with smartphone and laptop tools, and eager to contribute to AI model training, voice technology, and data evaluation projects.
