Head of Development in Munich, Germany

About Me

Hi, I’m Chris, and I’m a Software Engineer from Munich, Germany. I focus on Back-End Web Development and CI/CD to bring reliable products to users. I studied Business Information Systems (M.Sc.) at the Technical University of Munich (TUM) and wrote my final thesis at Stanford University, but I’ve learned most of the interesting stuff through my own projects and my desire for new experience. Programming as a craftsmanship is my main hobby, learning something new keeps me motivated. I’m currently working at Passcon GmbH as the Head of Development. On the web you’ll find me as @arubacao.
