Mobile application development<\/p>\n

A third year computer science student wrote to me: \u201cI have one more year before graduation but I am worry because there are many college graduates without job in my country. I do not know what skills do I need to have to ensure that I will have good job? I also have a brother who will go to college next year. I do not know what to advise him beside tell him to read your blog. My parents work hard to send us to college and I do not want to disappoint them. Please help.\u201d<\/p>\n

 <\/p>\n

Answer: \u201cYou have selected computer science which is the right field of study so you should NOT worry too much. There is a shortage of skilled workers all over the world and also in your country. As long as you have the skills, you should do well. If your brother also selects computer science, software engineering or Information System management than he should also NOT worry because the high demand for graduates with IT skills will continue in the next five to ten years.<\/p>\n

Since you have one more year in college, my advice is to focus more on mobile application development. Today there is high demand for people with skills in mobile applications (iOS, Android and Window 8). In the U.S, Android developers jobs have increased over 300% in 2014 as compare with 2013. There are over 6000 unfilled mobile developer jobs in April 2014 and the number is expected to rise higher. A similar problem also happens in Europe and Asia due to the explosion of demand for mobility skilled workers. It is not just technology companies are hiring mobile skilled workers but all kinds of companies are hurrying to develop mobile apps because soon mobile devices will replace personal computer as the main devices for everything. As computer science student, you probably learn about Web development and Java programming using PC platform already so it is relatively easy to switch to mobile platforms such as Android and IOS. Of course you need to understand the constraints of smaller screen and touch interfaces of mobile platforms. For example, when you build Web applications, you have the whole laptop screen but mobile screen is much smaller so you must learn to think differently about the features that you will build because the way people interact with a laptop is different than the way they interact with a smartphone or tablets. You cannot use drop-down menus or help screens in smartphone as it works in laptop. Smartphones do not have much memory and weaker processor than PC so you must be more conscious about your programming style. Beside the skill in Java, you need to learn HTML5, IOS, Android, XML etc. I have written several articles about mobile application development in this blog and you can review them.<\/p>\n

As technology changes, demand also changes so the best way to ensure a long career is to monitor industry\u2019s trends and continue to learn new skills to meet new demand. As long as you are willing to learn, you should NOT worry too much. I think you and your brother will do well and make your parents proud. Good Luck.<\/p>\n","protected":false},"excerpt":{"rendered":"
