He created a complete new Android app for us, integrating Firebase and even working with Bluetooth Beacon Devices. This was only a job for an expert and Sun X. delivered as asked. The communication is great and very clear even though we both lived on the other side of the world. Sun X is very kind and offers great help until the end of the development of the project, to make sure it also works on your computer. It was a pleasure to work with him and we will definitely work with him in the future again!”
