David conducted some user research testing on my company's website. His work was followed by a detailed report, which he went through with us extensively. His findings were both informative and eye-opening. As a result, we have made some significant changes to the website which have had significant results. I would highly recommend David for any job regarding user research, testing or web analytics. He is professional who has obvious knowledge of the subject and provides great results.
