Mobile apps are becoming more and more popular, especially in the workplace. They can help make employees more productive by providing them with the information they need to do their job better.
Due to the increasing popularity of mobile apps, more and more people are getting interested in investing in them. If you are one of them, you must learn the role and responsibilities of an app developer.
Knowing about the roles and responsibilities of app developers can help you write a perfect app developer job description and hire a better app developer as you know what to expect from them.
The role of an app developer varies depending on what kind of company they work for or if they freelance, but there are some responsibilities that all developers will have in common.
In this blog post, we’ll discuss some major roles and responsibilities of app developers. So let’s get started.
Understanding What Type of App You Want
The first and foremost important thing for an app developer is to realize what you want from him/her as a client. Understanding a client’s requirement is necessary for a developer to create the required features of an app.
If a developer fails to understand this, he/she will not be able to create the required features and it may lead to a loss of money for both parties.
Designing User Interface (UI) and User Experience (UX)
Another important thing that should not go unnoticed by any mobile apps developer is designing the UI and UX of an application.
Both these factors play a very vital role in determining its success among users as well as other stakeholders including investors too.
A good-looking yet functional design helps get more downloads while making money at the same time. On the other hand, if a mobile app is not user-friendly and easy to use, it will surely receive bad reviews which could lead to the failure of the app.
This is why every developer must keep in mind that UI and UX design plays an essential role before developing any application. Anyone who does not understand this would face problems later on during its launch as well as post-release stages too.
So, that could be an important skill to add to your job description and ask during the interview process.
Creating a Design Prototype of App
An app developer is responsible for creating a design prototype of the app to give you an idea about how it will look in reality.
Usually, this is done using simple wireframes which are created by hand or with software that can help speed up the process.
The developer should have knowledge of various UI and UX tools including sketch files and prototyping software like UXPin, Justinmind, etc.
Creating a prototype of the app before launching the complete version will help you understand if the app is user-friendly or not.
It’s also helpful to check whether all required features are working properly and no other feature has been left out.
Developing Code for the App
This is the main part of the developer’s job. They will use various programming languages to develop an app like Java, Objective-C, etc.
The language used should be selected according to what features are required by the app and which platform it is being developed for.
If you want your application on Android and iOS platforms at once, then developers must know how to create applications using cross-platform tools such as PhoneGap or Titanium Studio that help them build apps faster than before with less coding effort.
If you want to create a website then make sure to hire a developer who knows PHP. You can use a PHP developer job description template if you want to hire a talented website developer.
Debugging and Troubleshooting the App
The developer needs to be able to debug and troubleshoot any problems faced by end-users. This requires good technical knowledge of the application.
An app developer needs to ensure that the app is safe for end-users as well as secure from cyber attackers who can access sensitive user information or hold their device hostage until a ransom is paid.
For this purpose, it will be necessary for developers to follow best practices in development such as using encryption algorithms that are considered unbreakable even if someone has physical access to the data on your server with them being unable to decrypt it without having access keys, etc.
Testing the App Before and After Release
The developer should test the app for bugs, glitches, and other errors before as well as after launching the app. A QA team can also be used to do this task before release.
Testing the app before launching is an essential step of app development as it assures the quality of the app. It also helps in identifying bugs and issues with the app.
After launching, the app should be tested for any errors in its functionality or crashes after a particular time interval.
This will help in providing good customer support to your users who face problems using the application. It is also helpful when you want to release new updates to an existing application.
Performance analysis helps developers identify areas where they can improve performance through code refactoring and changes such as reusing memory objects instead of creating them again and again which adds up during execution time thus slowing down the entire process.
Documenting App Design and Code
Documentation is also an important part of app development.
You can use tools like Adobe Illustrator or Sketch to create mock-ups for your applications and then generate the documentation using these drawings with help from any tool that converts the design into code.
A developer should be able to prepare documents or handbooks of the application that can guide new team members on how to use the app. Documentation is also necessary for the future maintenance of the app.
