In the meantime, by writing unit tests, we have increased average code coverage from 10% to 60%.
In addition, in less than two weeks, I developed an SDK for one of our US customers to connect to BLE devices, allowing the project to be released ahead of schedule.
I am familiar with integrating third-party SDKs such as Stripe into applications. I've also used Lalamove (a delivery service) and Paymongo (a payment service in the Philippines) in applications.
We created an online drugstore in the Philippines, and it will be available soon after the client obtains a government license.
One of the most well-known sporting applications (AV) in Iran, designed and produced by us at Vasl, is promoted on TV and VOD platforms.

Persian tools

PersianTools is a stand-alone Swift library that enables the use of Persian features in Swift.
It's an open-source project available on Github.
I attempted to write it using the TDD method.
It's integrated with Travis for continuous integration and uses coverage to track code coverage.
For the time being, the package is also published on cocoa pods.


The Fanasan application is an Online Supermarket that operates in Iran, offering various discounts on various products.
To develop the application, I used the MVVM architecture and gitlab for source control.
Singleton, Factory Method, Chain Responsibility, POP, Adapter, Repository, and publish to test flight using Fastlane with gitlab ci-cd are the tech and design patterns that I used.
Unfortunately, the application was removed from the App Store due to a sanction.
