UNT business student Anna McKee was the first woman to win IBM's collegiate coding contest, Master the Mainframe, last year -- and now, she's done it again. McKee's win marks the third consecutive time a UNT student has won the competition. McKee is one of two winners and the only woman to win this year for the North American region. She also was ranked in the top three competitors globally, and was the only woman in the winning group.
