The team addressed Stfalcon with the task to integrate one more sales channel and the web interface. As a solution, our team developed an interactive app with three main sections: Station, Booking, Information. So users can find all requested information in a few clicks and without registration.
Review: We could arrange such kind of work where the process of development solves much more business problems rather than creating any. This is a very valuable feature to have when you are developing a startup.
