Graduated with a Bachelor's Degree in Computer Science & Engineering from the German University in Cairo, then completed an Advanced Master's in Artificial Intelligence from KU Leuven, Belgium. Worked as a Teaching Assistant for one year, teaching Prolog/Haskell/Natural-Language-Processing. Following that, I worked as a Data Scientist for 1 year at a travel-tech company, ended up managing it for another year, then landed at Preventia Technologies where I've been leading the tech team since then. What drives me the most is making a difference, wherever I work, and whoever I meet.
