Hakan Yıldız

Computer Scientist


Short Info
I left University of California and joined Microsoft as a Software Engineer in August 2014.

A small note on the "ı" in my surname:
The letter "ı" used in my surname is a lowercase "Turkish dotless i" ({\i} in LaTeX, ı in HTML and U+0131 in UTF-8). Consequently, Yıldız and YILDIZ are the correct spellings for my surname.
