concerned about keyword overuse on categories page

i’m getting concerned about the number of mentions of “website design” on my portfolio page you see here. and i have more categories too that i want to add.

should i be concerned about search engines getting pissed off because the keywords are mentioned too many times or are they smart enough to recognize that these are menu items on just one page of the site and they’re there (in their descriptive nature) for the visitors benefit???

please advise. thanks in advance!
