What does a mobile developer do?

Developer for mobile does more than just write code. His tasks on the project are much broader and cover almost all processes related to the design and creation of applications for Android and iOS. His responsibilities include:

• Architecture design. Determining the structure of the application, selecting suitable technologies and tools for its technical implementation, as well as planning an architecture that will ensure optimal page loading speed and the possibility of further development of the project.
• Application interface development. Creating an attractive user interface, in accordance with UI/UX principles and the latest trends in mobile development.
• Writing business logic. Development of the functional part, which includes data processing, interaction with the server, implementation of algorithms and logic of the mobile application.
• Working with local data. Implementation of functionality for storing data on the user's device using SQLite, Room (for Android), Core Data (for iOS) or other similar tools.
• Security. Organizing the protection of user data by encrypting information during storage and transmission, as well as introducing advanced security protocols.
• Application optimization. Improving code efficiency to speed up page loading and reduce device resource consumption - battery, memory and processor.
• Testing and debugging code. Writing and executing unit tests, conducting integration and UI testing to check the functionality of the functionality and identify possible errors, as well as eliminating detected problems.

Mobile developer skills and technology stack

For mobile development, various technologies and programming languages are used, which allow you to create functional applications for the Android and iOS operating systems:

• Swift. Apple programming language used by iOS native developers. Swift compiles to native code, which ensures high performance and responsiveness of applications. Additionally, it is Objective-C compatible, making it easy to migrate existing projects.
• Kotlin. The main language for native development of Android apps. It provides built-in security, supports coroutines that make it easy to write asynchronous code and work with threads, and is fully compatible with Java and can be used with existing Java code and libraries.
• Flutter. A development kit running on the Dart language, which is widely used by cross platform mobile developers to create applications that run simultaneously on iOS and Android. It significantly saves budget and development time, while providing high performance, which is almost as good as native Swift and Kotlin.
• Java. One of the main languages in the mobile developer's arsenal is Android, which is used to create native applications.
• C++ . Typically used in conjunction with engines such as Unreal Engine to develop mobile games with high performance requirements.
• React Native. An open source framework that allows you to create cross-platform applications using JavaScript and React.

In addition to programming languages and frameworks, to successfully implement applications for iOS and Android, a qualified mobile developer must also possess other technical skills. Here are the main ones:

• Database. Knowledge of SQL and experience with SQLite, Room (for Android) and Core Data (for iOS).
• Cloud technologies and backend. Skills in working with cloud platforms such as AWS, Google Cloud, Firebase and basic knowledge in backend development.
• APIs and integrations. Ability to work with RESTful and SOAP APIs.
• Understanding mobile platforms. For iOS development - knowledge of UIKit, Swift UI, Core Data, Foundation framework; for Android development - Android SDK, Jetpack, RecyclerView, Activity/Fragment lifecycle.
• Version control. Ability to use version control systems such as Git.
• Testing. Skills in writing and running tests: JUnit, Espresso - for Android, and XCTest - for iOS.

How to properly check the competence of a mobile developer

As we have already figured out, to create modern and functional mobile applications for the iOS and Android platforms, the developer must master many technologies and tools. Therefore, before hiring and including a specialist in your team, it is very important to make sure of his qualifications. Here are some methodologies that will help you objectively assess candidates' knowledge and skills:

• Portfolio analysis. Study the developer's previous projects. These could be apps on the App Store and Google Play, or code samples in public repositories such as GitHub. This way you can evaluate the candidate’s coding style and the final result of his work.
• Technical interview. Conduct technical interviews with candidates and ask questions related to the technologies you plan to use in your project. It is also worth clarifying their knowledge of application architecture, design patterns, and experience with APIs and databases. During the interview, you will be able to evaluate not only the Hard Skills, but also the Soft Skills of specialists - how they explain their decisions, answer questions, present their experience, etc.
• Practical task. Offer candidates a short test task related to application development using the technologies you need. For example, this could be a task related to the implementation of specific functionality or fixing problems in existing code.

How much does it cost to hire a mobile developer?

The cost of developing a mobile application can vary greatly and depends on many factors: the expertise and experience of the developers hired, the complexity of the product, what platform you are creating the application for - iOS, Android or both operating systems, as well as the planned time frame for entering the market.

Each mobile application development project has unique requirements, and without understanding these specifics, it is almost impossible to create an accurate budget. The cost is usually determined based on the hourly rate of the specialists involved - this allows more flexibility in managing processes and adjusting the scope of work during the implementation of the application. There is also the option of a fixed fee per project, but this is used less frequently as it can lead to delays and additional costs due to the need to renegotiate the terms of the contract when new ideas or unforeseen tasks arise.
