    “I hired Valentin to build my first app. Throughout the process Valentin always explained what he was doing, and kept me informed of his progress. He also suggested improvements to the design I had come up with, which made the app better than I had realised was possible! He even came up with some new ideas that I had not thought about. He was also quick to address my feedback, and was flexible when I slightly changed the details of the app. Lastly the quality of the finished app was fantastic! Therefore I highly recommend Valentin to others who are looking for a high quality Freelancer :)”
