In April 2016, the owners of Yami Yami came to us and asked us to make the best delivery application with a lot of functions and to complete the project in time by September 1. We could not abandon existing customers and honestly said that we could finish only in mid-September. For Yami Yami, the difference of 2 weeks was critical, and they found another contractor.
All summer long, the owners of the service told us about the development process, shared the problems, asked for advice. We talked, consulted and brainstormed together on what can be improved.
As a result, the developers released the application not in September, but in December, and there were many shortcomings in it. In the iOS version it wasn't possible to make an order, and it was hard to even enter in Android.
Then the client turned to us again, but the task was different.
