I worked with David on my project and I greatly appreciated his professionalism. What I particularly liked is that he really took the time to understand my project. Even before the start of the service, he did research to verify the technical feasibility of what I wanted to implement. He even sent me a screenshot to confirm that it was feasible as it was quite technical. It was this involvement and seriousness that motivated me to work with him.
