Youssef Mustafa
@youssefmustafa
I build responsive React interfaces and improve AI models through quality-focused evaluation.
EgyptWhat I'm looking for
I've contributed to AI training projects at Outlier AI and Alignerr, designing and refining LLM prompts, evaluating generated responses, and delivering structured human feedback for model improvement.
At Outlier AI, I localized models and prompts into Egyptian, Saudi, and Levantine Arabic, improving cultural relevance across reasoning, content generation, classification, and response-evaluation tasks. I also identified edge cases and iterated on prompt structures to support more reliable outputs.
I'm a frontend developer focused on clean, responsive, interactive web applications using React and modern web technologies. I use AI tools professionally to streamline development workflows and keep learning.
I've also built an Arduino-based sign language translation glove that captures hand movements through flex sensors and motion detection, converts gestures into text, and produces spoken output to support deaf and mute individuals.
