I have done database work for 3 major oil companies, 2 major entities on wall street, many fortune 1000 companies, several fortune 500 companies, 1 fortune 100 company, many individuals, many small businesses, and one very large national insurance company. I wish I could list all names, but most of them have me sign a non-disclosure statement before awarding the bid. I have always kept my word to them, and won't change that.
