About Me

I was born in Southern Germany and studied Applied Computer Science (Bachelor) at the University of Applied Sciences in Constance. I then moved to Stuttgart and studied in Computer Science & Media (Master) at the Stuttgart Media University. While having various interests in different areas of Computer Science, my biggest passion is developing consumer apps.
