Jonathan Hillebrand, 31

Indie iOS and Web developer.

I sketch, develop and publish apps for iOS, Android and the Web. A total of 7,091,144 people downloaded my apps so far. My best selling app is a geography game called Where is that? which helps children and adults to learn about the world.

I started my first website at the age of 12 and built a homepage builder with 30.000 users during highschool. This resulted in my first internship at SAP when I was 14 and I worked there part time during highschool and the first years in the Business Administration masters programme at the University of Hamburg. Eventually my interest turned to Investment Banking and I worked at Dresdner Kleinwort, Goldman Sachs and Commerzbank. Given the state of the banking world I decided to switch back to my passion and started my own full time app business.

Now I do what I love and that's where you excel. I have the freedom to travel the world with my wife, who is a management consultant. That's were I collect my ideas for new apps. My approach as an Indie developer is to start with a great Minimum Viable Product (MVP) and then take the successful ones to the next level.

I am also available for Freelance work, if you need help with your next exciting app project.

Before I started JAYSQUARED, I worked for these companies.
