PassTo
https://apps.apple.com/us/app/passto-global-money-transfer/id1354449369PassTo is an international money transfer application available for iOS and Android with more than $2.5 million in monthly transfers.
The app was initially developed natively for both iOS and Android, and I converted it to Flutter. I started by creating the architecture and the technical design of the project, and at the same time, I trained the team on how to implement high-quality apps using Flutter.
The team now focuses on shipping more features with very high quality instead of wasting time developing the same feature twice for both platforms. The new features are now shipped very fast compared to the previous versions. The team is now focusing not only on the feature development but also on the quality of the feature.
The app is 100% technically designed with all the required details, so the new changes are welcomed. The testing coverage of the app is more than 90% as we implemented unit testing, widget testing, and integration testing. As a result, the issues reported by the testing team decreased drastically. Also, the app distribution time and effort have been dramatically reduced because of the implementation of CI/CD pipelines.

Events Access App (NFC)
All the event attendees receive an NFC bracelet on the registration counter, and this bracelet is configurable via the app as the following:
• The admin on the registration counter enters the attendee info, including name, email, and phone number, and defines the access level based on the ticket type.
• The app defines the rooms and areas allowed for a specific attendee to enter based on the ticket type.
• On each gate, an admin scans the bracelet, sees the access information, and the app logs the attendee info on the server automatically. It is done via AppClip, so there is no need to have the app installed on the admins' devices.
• This info is used to gather stats on the session attendees and send them the specific session materials via email later.
I created the application from scratch until I shipped it to AppStore. I used Swift, SwiftUI, Core NFC, App Clips, and RESTful APIs.
