Mobile Application Development Courses. Mobile Developer Mobile Application Development Courses Online

Anyone can learn how to develop applications for mobile phones and tablets. Now any Internet user will be able to earn money doing what they love. If you not only like to use various applications, disassemble their nature and structure, but are also interested in creating them, you need to take online development training mobile applications from our experienced professionals. Today, technology is constantly evolving and does not stand still. Video courses are a great alternative to the usual types of training, they also provide an opportunity to get a new exciting profession without studying at a university and gain good knowledge and skills.

Mobile App Development Online Courses

Mobile app development courses are required for:

• improving one's own qualifications;
• acquisition of knowledge from scratch;
• familiarization with the specifics of the applications, with their device;
• self-creation of mobile applications for Android or IOS, as well as for other popular systems.

If you are familiar with the IT field, but want to acquire a new profession, such courses will be an excellent solution for retraining. Become an Apple or Android device specialist. According to statistics, Android-based products are now leading the IT technology market, and therefore retraining from a system administrator to a developer of mobile software and applications is more relevant than ever at this time. Courses on creating mobile applications will help inexperienced users to get the whole range of knowledge and skills, and in the future will be a great start to your career. You can earn not only in a company, but also on a freelance basis, while at your computer at home. After our courses, you will receive a certificate confirming that you have all the necessary skills. If you wish, you can not only get training, but also become a teacher by recording your course!

Whether you like it or not (it's possible that you don't care at all), the mobile app market is growing and expanding. More and more people cannot 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 become an integral part of our daily lives.

This trend seems to be quite long-term at the moment. 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 money.

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

Where to learn

I must say right away, do not 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 mentors that will become the first criterion in choosing a school. The educational portal GeekBrains has 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 duration of the courses is another plus. It will take about a year of high-quality and regular work to study a completely new direction of activity and delve into all the subtleties.

If someone promises to teach you how to create mobile applications in a month - do not believe it, it is impossible by definition.

Finally, specify how things are going with the further employment of graduates. Will you be offered an internship or 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 specialists from the educational portal.

Mobile developer is a specialist who develops software applications for various mobile devices: tablets, smartphones. The profession is currently the most fashionable, promising and in demand. After all, it is in the field of mobile development that such interesting novelties as a voice and gesture interface have appeared. The profession is suitable for those who are interested in computer science (see choosing a profession for 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 is no longer imaginable without mobile devices, which are used not only by advanced youth, but by all segments of the population. More and more people access the Internet from mobile devices. The Russian market of mobile devices is the fastest growing. The man of the future does not want to be tied to the office with his heavy computer equipment, when there is a real opportunity to solve any issues using mobile devices literally on the go.

Lots of computer programs relocated to mobile devices and successfully operates 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 of 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 various levels. If the 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 currently not clearly defined due to the youth of the profession. He has to be a designer, coder, programmer at the same time. In general, the activity of a mobile developer can be divided into several stages:

• the preparatory period in the creation of the application - the definition of specific customer requirements in the form of technical specifications;
• creation of 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, versatility, 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 facilitate the design part of the work of a mobile developer. Guidelines are detailed descriptions of elements in mobile applications, and they are different for each platform.
3. The resource investment for mobile development is low.

Minuses

1. The policy of companies producing mobile devices does not allow the developer to quickly make changes to the application, since any action is checked by company employees. So, Apple is checking for any update within a week.
2. Pickiness of users to the design and functionality of applications delivers a lot of unpleasant moments.

Place of work

There are no borders in the IT-sphere for a long time. You can work from the comfort of your home for any multinational company in the world or a private business. Jobs for a mobile developer can be found on freelance exchanges, on 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 constructively respond to criticism from users who leave their feedback on the work of applications in Google Play and the 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:

• analytic mind;
• attention to detail;
• high efficiency;
• ability to plan and meet deadlines;
• striving to improve professional skills;
• study of new technologies for mobile operating systems.

Professional skills and knowledge

knowledge of programming languages:

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

Mobile developer training

International educational institution, conducts training. Works since 1999. 42 branches in 16 countries of the world. The largest authorized training center for Microsoft, Cisco, Autodesk. Students receive international certificates and an international diploma. The main goal is the employment of each graduate.

The peculiarity of mobile applications is that they are created using ready-made solutions like a constructor. This makes it possible to obtain the necessary education in the shortest possible time by completing special courses. Many experienced mobile app users learn how to develop mobile apps on various Internet services on their own, but it's a long process of trial and error, which is best done under the guidance of an experienced developer. In addition, the theory should immediately be supported by the practical application of the acquired knowledge, which is provided for by 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.
