As of now, I speak these languages:

Currently, I am studying at the 42 Heilbronn.

The 42 Heilbronn is a coding school with a completely new educational design: Everyone is learning from everyone - without teachers. This peer learning principle challenges the traditional education system very successfully.
More information can be found on their website: 42heilbronn.de. My 42 intra profile can be found here.

I started my journey in the world of coding back when I was 12 years old using the Java Programming language. Later on, I added another language to my portfolio, the Swift Programming language. At the 42 Heilbronn, I learned the C and the C++ Programming languages.
