In general, I think this advice is off. Particularly, "don't use a word other than made." Using developed, designed, implemented, deployed, or a variety of other words that have slightly different meaning to indicate what your actual contributions were makes sense. In general I think made is imprecise, and makes whatever the object that was created appear simple.

I also think that if you have a GPA that is worth being proud of you should include it. It takes up very little space, and it summarizes years of accomplishment in a quantitative way. I'm more than 10 years out of my undergrad now, but I'm still going to say that my GPA was 3.98 (4.0 in majors).
