When the work is done, the music starts.

I'm Vito. Computer science at HHU Düsseldorf with a focus on machine learning, then full-stack work for startups and DAX-listed companies. Years in bars and restaurants taught me to stay calm under pressure and to read a room. Right now I'm training to build 3D animated websites like this one. It's fun, and it shows my creative side.
