• Programming fundamentals
• Application architecture and deployment
• Third-party service integration. API
• Testing. Quality control
• Performance and memory optimization

1. Programming fundamentals

For iOS developers, this is Swift or Objective-C.

For Android, it is Java or Kotlin.

If you specialize in cross-platform solutions, knowledge of Dart (Flutter) or JavaScript/TypeScript (React Native) will be indispensable.

When describing app developer skills, don’t limit yourself to general phrases.

Your knowledge of Flutter, React Native, or Xamarin can demonstrate your versatility.

2. Application architecture and deployment

Every mobile application developer should be familiar with modern design patterns. In particular, 

• MVC, 
• MVVM,
• Clean Architecture. 

This allows you to develop scalable, easy-to-maintain applications.

Successful mobile app developers know that a high-quality application is also a stable system with continuous integration. Git, Jenkins, Fastlane, Bitrise are not just buzzwords, but tools that ensure fast updates and product quality.

Despite this, many skilled people are unable to obtain the job they desire simply because their CV is inadequately constructed.  If you want your resume to be more than just a list of talents, but rather a compelling self-presentation tool, don’t be afraid to seek professional assistance. In particular, you may turn to a computer science resume writing service and get an expert approach to creating resumes specifically for technical professionals.

• Chats,
• CRM, etc.

4. Testing. Quality control

Testing skills are a key marker of the work quality of experienced app developers.

A mobile developer should:

• Create unit tests for application logic,
• Use UI tests,
• Understand the basics of CI/CD for automatic deployment and testing.

All mentioned answers the question What do mobile app developers do? They not only code, but also guarantee quality.

5. Performance and memory optimization

Users expect an app to be fast and not drain their battery. Therefore, mobile application developer skills needed necessarily include:

• Memory usage profiling,
• Reducing CPU consumption,
• Minimizing background tasks,
• Lazy-loading images.

These skills are especially valuable when compiling a mobile application developer resume, when you need to emphasize your ability to develop an optimized application.

6. App publishing and support

Real good app developers have a full publishing cycle:

• Building versions,
• Preparing metadata for the App Store/Google Play,

• Responding to user feedback,
• Releasing updates.

2. Soft Skills

Good mobile app developer skills also include soft skills.

Can you explain a complex technical concept to a non-technical client? This is a significant advantage.

3. Time management

Mobile app development requirements often include working to deadlines. Your ability to work with Agile, Sprint Backlog, and complete tasks on time is just as valuable as knowledge of Swift or Kotlin.
