Our task was to provide a full testing and fix critical bugs. We tested the application and sent our client a full report with our recommendations. A client defined the scope and priority of the debugging process. As a part of our developing scope, the app uses an extension to a browser that processes the pictures from a selected web page and transfers them to the app. This part was challenging. In addition our developers should be integrated into our customer’s team and work for a mutually beneficial solution together.
We did all the full scope of testing activities, provided the report and our recommendations. Our customer appointed the tasks for debugging that we completed. We were engaged in the development of a browser extension for processing pictures where we connected JavaScript, Swift, and Objective-C in one codebase.

A user can use a QR-code to confirm the order when checking out. Several payment options are available, including payment in the store. The same is true with the delivery, a user can pick up his order in the store by himself. Engineering of logics, development, payment implementation, as well as geolocation and other features supposed to be the next stage of the project.
