PassTo 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.

Slide is the fastest way to earn cash back as users shop in-store or online. When paying with Slide, they can instantly get up to 10% cash back at hundreds of retailers and restaurants.

The app was developed in Flutter. I created the app architecture, the technical design and helped the team in the implementation process to adopt the best coding practices to deliver a high-quality application that is testable, maintainable, and extendable.

BlaBla Connect is an international calling application, and it's one of the biggest apps I started from scratch. It contains a lot of technologies and features, including:
• GSM and SIP calls using PJSIP and G.729 codec;
• VoIP calls using WebRTC and Opus codec;
• chatting using XMPPFramework and ejabberd server;
• mini calls and future calls; and
• airtime top-up.

ACTIVITIES
• Collaborated with various stakeholders to determine the functional and non-functional requirements for the app.
• Selected the technology stack, including the chatting server, call server, and the mobile frameworks needed to fulfill the requirements.
• Provided high-level and low-level technical design documents to the team.
• Identified the coding standards and the quality matrix.
• Mentored the team during the whole process.

The company launched the app and acquired more than two million users. The revenue stream is growing, and the app design and architecture allow the company to add new features quickly.

RentZero enables renters to earn extra income by creating a neighbor-to-neighbor marketplace that allows neighbors to do helpful tasks for each other and, in doing so, reduce their rent, ideally to zero.

RentZero offers renters multiple ways to quickly and easily earn extra income to reduce rent. Examples include doing tasks for neighbors, such as dog walking, errands, ride-sharing, babysitting, renting out a spare bedroom, providing professional services like tutoring and training, subletting parking spaces, and getting a bonus for referring in a new tenant.

I developed the app from scratch until I shipped it to the App Store.

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.
