Surf task was to develop an e-commerce app for iOS.
We created the UI/UX design, built a REST API to integrate the app with the backend, and developed a native iOS app — and those were the times of Objective-C.
We’re writing this case in 2020. The O’key app was built in 2015 and is still working. For a mobile app, 5 years is like 120 in human years. This app is an old timer.
O’key brought forward the first grocery delivery service in Russia. Right now the delivery service is a huge and highly competitive industry. However, even in this context the app successfully functions using the same design and code base we put in place five years ago.
