I'm a young app developer, for Android and iOS. I've worked on apps for JimmyFM (a small Dutch radio station) and Thinking Cleaner (The Android version, ThinkingCleaner.com)
I've started programming when I was about 12 years old, when I went to the secondary school. At my school we had a website where we could check our roster. But I thought: "Why not make an app for that!". And I started working on it (for Android, Because Apple was far to expensive for me...)! A simple roster app for me, it wasn't my intention to publish it. When I was using the app in class, a teacher noticed it. After a lot of emails to school employees, I got in touch with the rector and we talked about the app. She really liked it and she said that I can publish the app for the whole school (1500 pupils)! That was an amazing time for me, my very first app...
