Freelancer Overview

I am a freelance engineer with hands-on experience in data annotation, prompt engineering, and AI training data projects. I have managed multiple projects simultaneously, focusing on designing prompts to test AI models and improving response accuracy through careful comparison and evaluation. My expertise includes localizing and annotating data in various Arabic dialects—Egyptian, Saudi, and Levantine—making me adept at handling linguistic nuances for NLP and AI applications. With a strong background in programming, mathematics, and encryption, I am committed to delivering high-quality results on time and collaborating effectively with diverse teams to drive innovation and excellence in AI model development.
