Jay Ramos

Jay Ramos tried to run away from his destiny, but it proved to be in vain. After stating his goal to become “a computer programmer” in fifth grade, Jay attended Yale University where he majored in (naturally) history. After a brief stint teaching history and math to middle schoolers, Jay finally gave in to the technology voices in his head and entered the Information Technology field. At The University of Texas, Jay worked in a number of different areas and technologies. He has continued his career in IT after making a big move from Austin to Green Bay, where he works as the Technical Lead for the Web Team at Schneider.
