      Mobile App Development Review from Mica Palmer

      They helped us solve issues. They designed an app for us.High level/quality of client attention and interaction. All communications, information exchages, and client servicing were well-conceived and well-executed. They kept me on my toes to provide them the information they needed from me. They kept excited about the project and, because of that, kept me optimistic and driving toward the success of my project. The culture of coaching and support they provide start-ups. They don't sleep well unless they know you have all the tools and chops to obtain success. I've never seen any other company provide such rich and valuable deliverables along with ingenious and compassionate client support. Kodevent is a beacon of know-how and wisdom in an otherwise dark ocean for any start-up that is hoping for success.

      eCommerce Development Review from Devul Nahar

      We needed help designing the Frontend pages on my website. Also some design work. Everyday I would assign my Frontend developer some key tasks and deliverables. He would report back to me. An example of key deliverable he did was help design the logic of flow of grading when we have multiple types of questions. They were quick to respond and professional. They had great professionalism, good talent, and good support.

      Web Development Review from Peter Wallace

      Kodevent and their team were always great at communicating with our team. They worked very hard to finish tasks in the allotted time frame. When we had requests or changes, they were always quick to find a superior solution. Our project is still ongoing, but they are waiting on our side of things to complete and go live. I am appreciative of their great communication skills. They were always quick to respond and worked within our time frame.
