Kei Yang and his team were fantastic to work with. He laid out a detailed timeline with clear dates and milestones that made it easy for progress to be tracked and quantified. He communicated promptly and professionally, and was able to take the feedback that was given to him to make the necessary changes in our project in a very timely and efficient manner.
