Mobile developer is a specialist who develops software applications for various mobile devices: tablets, smartphones. Profession on at the moment the most fashionable, promising and in demand. After all, it is in the field of mobile development that such interesting new products as voice and gesture interfaces have appeared. The profession is suitable for those who are interested in computer science (see choosing a profession based on interest in school subjects).

There is an acute shortage of specialists in this profile on the job market. And in the future the situation will only get worse, since the modern world can no longer be imagined without mobile devices, which are used not only by advanced youth, but also by all segments of the population. More and more people access the Internet from mobile devices. The Russian mobile device market is the fastest growing. The man of the future does not want to be tied to the office with its heavy computer equipment, when there is real opportunity solve any issues using mobile devices literally on the go.

Many computer programs moved to mobile devices and functions successfully there. And in the future their “mobilization” will only intensify.

The advantage and uniqueness of the profession of a mobile developer is that everything depends only on you: having an initially good idea and competently implementing it into the world mobile technologies Without investing resources, you can create an international project similar to Instagram in the shortest possible time and become a millionaire.

Mobile applications are extremely popular among entrepreneurs of all levels. If an application is relevant, easy to use, functional, and solves important user problems, it will significantly increase the number of customers and increase business profits.

Features of the profession

The functional responsibilities of a mobile developer are not clearly defined at the moment due to the youth of the profession. He has to be a designer, layout designer, and programmer at the same time. In general, the activities of a mobile developer can be divided into several stages:

• preparatory period in creating the application - determining specific customer requirements in the form of technical specifications;
• creating a mobile application that combines such mandatory qualities as trouble-free operation on one of the mobile operating platforms ( Apple iOS, Google Android, Windows Mobile), convenient user interface, multifunctionality, profitability for the customer.

Pros and cons of the profession

Pros

1. A highly paid, in-demand profession.
2. The clarity of standards and guidelines greatly facilitates the design part of a mobile developer’s work. Guideline is detailed descriptions elements in mobile applications, and they are different for each platform.
3. The resource investment for mobile development is low.

Cons

1. The policy of companies producing mobile devices does not allow the developer to quickly make amendments to the application, since any action is checked by company employees. So, Apple checks for any update within a week.
2. Users' pickiness about the design and functionality of applications causes many unpleasant moments.

Place of work

There have been no boundaries in the IT field for a long time. You can work without leaving home for any transnational company in the world or private business. Jobs for a mobile developer can be found on freelance exchanges and job sites. Or you can create your own mobile application development business.

Important qualities

One of the most important qualities of a mobile developer is the ability to respond constructively to criticism from users who leave their feedback on the operation of applications in Google Play And App Store. After all, negative reviews are not always aimed at offending the developer. As a rule, they indicate some specific problems in the mobile application and the developer should solve them.

Required personal qualities:

• analytical mind;
• attention to detail;
• high performance;
• ability to plan and meet deadlines;
• desire to improve professional skills;
• studying new technologies for mobile operating systems.

Professional skills and knowledge

knowledge of programming languages:

• Apple iOS - Objective-C, Swift
• Google Android - Java, Scala
• Windows Mobile - C#, VB.NET;
• ability to create applications for Android, iOS, Windows Mobile;
• application debugging;
• knowledge of the basics of programming for iPhone and iPad;
• knowledge of new technology libraries
• for iOS - Siri, for Android - “OK, Google”;
• working with a SQLite database.

Mobile developer training

An international educational institution that provides training. Operating since 1999. 42 branches in 16 countries. Largest authorized training center Microsoft, Cisco, Autodesk. Students receive international certificates and an international diploma. The main goal is the employment of every graduate.

The peculiarity of mobile applications is that they are created using ready-made solutions like a designer. This makes it possible to obtain the necessary education in the shortest possible time by completing special courses. Many experienced users of mobile applications independently master the skills of developing mobile applications on various Internet services, but this is a long journey of trial and error, which is better to go through under the guidance of an experienced developer. In addition, the theory must be immediately supported by the practical application of the acquired knowledge, which is provided for in the course programs. The courses are taught remotely, which is very convenient in terms of saving time and money.

But even after completing the coolest courses, independent work on self-improvement of professional skills is necessary on an ongoing basis.

Lesson 10. Start up

We talk about our project and introduce the team in English.

Whether you like it or not (it’s possible that you don’t even care about it at all), the mobile application market is growing and expanding. All more people They can’t imagine their life without a smartphone, with which you can do anything: call a taxi through the appropriate application, transfer money, and finally, track your daily activity and count calories. These are the most banal examples that convey the essence of the phenomenon - mobile devices have organically entered our daily lives.

This trend currently looks quite long-lasting. There is simply no reason to believe that people will stop using smartphones and tablets en masse in the near future. Accordingly, they will need applications, games and all that stuff. So it turns out that mobile developers will definitely not sit idle and have no money.

Now is perhaps the best time to master this profession. The market is rapidly developing, but is not yet oversaturated with personnel, so you have a very real chance to offer your services and receive a decent reward for them. Don't you know how? Learn. :)

Where to learn

I’ll say right away, don’t waste your time and energy, go to the courses. Of course, you can try to figure out the intricacies of creating applications on your own, but this is an option for those who have absolutely nothing to do. Theory without practice is worthless, and it is better to apply knowledge in practice under the guidance of professionals.

Actually, it is the professionalism of the mentors that will become the first criterion in choosing a school. Educational portal GeekBrains gathered the best of the best: teachers from the country's leading universities, employees of large IT companies - in general, people who understand how things are in the industry and can tell others about it.

The impressive length of the courses is another plus. To learn a completely new area of ​​activity and understand all the intricacies, it will take about a year of high-quality and regular work.

If someone promises to teach you how to create mobile applications in a month, don’t believe it, it’s impossible by definition.

Finally, find out how things are going with the further employment of graduates. Will you be offered an internship or will you be sent to find your place in life on your own? GeekBrains gives you three options to choose from: work within an IT incubator, in one of the partner companies, or under the guidance of educational portal specialists.
