Bachelor Thesis


To get my Bachelor of Science graduation I certainly had to work on a bachelor thesis. During my last semester I got a mail from a team of students who are developing a football app (called Skamander) searching for web, app and backend developers. The mail sounded very interesting to me because I mainly worked on web applications or iOS apps in my free time and during my holiday jobs. So I wrote back and got a date for a interview. Because of my experience in app development I got recruited as iOS app developer. I worked there for a few months and finally got my grade for the bachelor thesis and most importantly gained further experience in running one-product-companies.
