    “I can only recommend to work with Sun X. He is an outstanding developer and it's a amazing to work with him. 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!”

    “This project was originally given a timeline for completion in 3 months. We waited 1 year, 2 months, before Sun X raised a dispute (on Freelancer) because he was unable to complete the project. We had issues with who we were dealing with, in that we awarded the project to a David Liu, then the project build was one Eric Li, then finally a dispute raised by Sun X. In fairness, there were difficulties with other technical support, but due to lack of communication; a lack of understanding of the scope we had agreed to; and a lack of technical knowledge - this project failed and we we were left with a half completed App to what was originally agreed to.”
