Yuchengco graduated from Assumption College with degrees in Liberal Arts and Education and earned a Masters in Business Administration from Ateneo University.
In 1992 Yuchengco founded Filipinas, a magazine specifically directed toward the Filipino American community. The magazine, in its prime, covered various topics such as the lack of compensation of Filipino Veterans in World World War II, domestic violence and Filipino identity. Yuchengco sold Filipinas in 2005 and it dropped its print version in 2010, existing solely online thereafter.
In late 2012 Yuchengco started a new magazine, Positively Filipino, that was solely available on the internet.
In 2014 Positively Filipino writers took six Plaridel Awards, boosting the magazine"s status.
