Freelancer Overview

As an expert in AI training and immersive technologies, I bring a unique blend of skills in data labeling, prompt engineering, and multimodal interaction. I have contributed to various AI projects involving logic-based task design, LLM evaluation, and puzzle-solving prompt creation, helping improve reasoning capabilities in frontier models. My deep background in mathematics, computer programming (Python, C#, Unity), and visual data processing (image/video labeling and polygon annotation) is complemented by hands-on experience with tools like Unity3D, Blender, and advanced cloud platforms. Fluent in Arabic, English, French, and Spanish, I’m well-positioned to work on multilingual data tasks, particularly in the context of text and speech understanding. My academic and research roles, spanning a PhD in collaborative virtual experiences and leadership in real-time holoportation development, enable me to combine technical precision with creative problem-solving. I’ve also led and managed multiple EU-funded projects, balancing technical depth with strategic execution across R&D, UX/QoE analysis, and immersive system development.
