" and "I have known Ahmet Üstün since 2013 in my capacity as a Lecturer for computing courses at Information Technology Graduate Program, Sabanci University. Throughout his studies in Sabanci University, I have taught Mr Üstün “Programming with Java”, “Advanced Java Programming” and “Mobile Programming” courses and witnessed his tremendous success and development. This development came not only in the area of information technology, but also in maturity and character as well. The academics at IT Program in Sabanci University are mostly challenging as the students not only attend lectures but are also working full-time at an institution like Mr. Üstün. Thus, they need to follow their routine work life and cope up with the university objectives at the same time. Mr. Üstün fulfilled all the requirements with the added challenge of honours and advanced courses. This challenge proves that he is capable of achieving success in a stressful environment."
