"We hired Keith after a long search to find someone to write requirements that can be used for proposals for an internal software system we hope to get made in the next year. Keith was very responsive right off the bat, and had a unique set of experience that we did not find in any other technical writer that we talked to. Keith worked quickly and efficiently, and took all of our feedback and integrated it into the document. He created nice flow charts to go along with the documentation. I would not hesitate to hire Keith again for our technical writing needs."
