Work History
iOS Developer
Cognizant Technology Solutions Corporation
10.2022 - 05.2023
- Participated in design sessions for an in-house application with SOLID principles as the guideline for maintainability, scalability and testability
- Developed part of an iOS application using Swift and UIKit using SnapKit as the layout framework
- Wrote Unit and UITests for various ViewControllers, Networking and business logic code
- Developed networking code using Apple's new async-await api.
Senior iOS Developer
Adanic Afzar Co
06.2021 - 05.2022
- Successfully extracted navigation responsibility from all View Controllers to use Coordinator design pattern to improve code quality by making it more extendable, reusable and testable and moving ViewControllers one step towards Single Responsibleness
- Successfully refactored data storage layer from Realm Database to Keychain to address security issues and reduce application size
- Having SOLID principles in mind, I used Protocols and Generics to decouple the storage layer from application logic that resulted in an easily maintainable code
- Because of this separation, we can now choose any database technology as we see fit by conforming the common data layer protocol
- Used swift's protocols and generics to create reusable UI Components to be used across the code base to minimize boilerplate code and improve maintainability, scalability and testability of the source code
- Refactored legacy code to change architecture from MVC to MVVM to achieve cleaner and more readable code and make it reactive as well
- Created CI pipelines using Fastlane to improve developers' productivity and achieve faster delivery of the software to production.
iOS Developer
IranKish Credit Co
02.2018 - 04.2021
- Responsible for Migrating code from Objective-c to Swift language
- I rewrote all objective-c source files with swift language
- Created a push notification layer to talk to apple APNS regardless of what third party library we use
- At the time, it was only OneSignal service
- However, it can now be any other push service like Firebase or Batch without much effort
- The layer contains a protocol that contains the necessary functionality required by the application and can be conformed to in case we needed to change the push service
- Used swift's protocols and generics to develop Networking functionalities as a separate layer for multiple applications
- This contained a generic function capable of talking to an endpoint regardless of the datatype expected by that endpoint as well as the http method used
- Responsible for publishing app to end users as well as company's enterprise customers outside app store using enterprise sign
- Developed a wrapper layer on top of a third party library which used delegation to handle callbacks and changed it to use Closures instead
- This made it extremely easier to work with the library as well as making the code more readable.
